# N.Y. Lottery Draws 9-1-1 on 9/11

N.Y. Lottery Draws 9-1-1 on 9/11 This is a pretty strange coincidence. Some people find coincidences everywhere. But, others say the world would be more surprising if coincidences didn't occur. Still, this is pretty odd. What coincidences have you experienced? Do you see meaning in them?

Hmm. A 1-in-1000 chance that the correct three numbers would be drawn on any particular date (of which only a subset fit the 3-digit format, allowing a middle 0). The cumulative probability over a year ... hmm ... probably about a 1/3 or 1/4 chance that this will happen to

Actually, I have an odometer on my bike, and that passed 911 today (I ride about 3 miles a day, so the coinciding numbers will probably never happen again). That was kinda weird.

Yes, that is weird. We must be witnessing some cosmic convergence of improbabilities around 911. Or more likely, someone rigged the New York lottery for a day. The chances that "911" would be picked on this significant day, the first anniversary of the attacks, in the state where the WTC collapsed... I'm not a statistician, but it's more than 1/1000.

If it were rigged, I can't say I disapprove, since in the absence of religion, coincidence has emerged as the one transcendent factor in atheist life. I suppose the effect of rigging the lottery would be to provide some solace to people who were affected by the tragedy. I suppose they see the hand of our famously reclusive God at work. God is with us.

Importantly, the only time in my life I've tried to guess someone's middle name, I was successful--Whittaker.

It is in fact exactly 1 in 1000. The balls they use for drawing the numbers don't know the date or what happened a year ago.

Incorrect. You're assuming that it's possible to come up with a number that would reflect the date every day of the year. But take December 13th....1213 isn't a possible number.

So there's a 1/1000 chance of drawing in a particular number....but there are only 273 days on which this can occur. (But do we count the dates like October 8th, which can be written as 10/8?)

Hmmm, indeed.

Then there's a 1 - .999^273 = .24 chance of it happening at least once during a year.

Incidentally, if you estimate that each date, like 9-11, has three permutations (not always true, 12/3 has 6 and 11/1 has 1), then there's a 1 - .997^273 = .56 probability of getting the right numbers for the date in some order at least once.

As an atheist, it makes me feel like I've fucked up.

Rigged perhaps. The need for people to think unrationally in these ~~~dark~~~ and ~~~confusing~~~ days is paramount to us accepting Christ as our Lord and Savior and also He who directs the hand of the black gold crusaders. We best believe in them.

I've said it before, I don't know nuthin' 'bout 'nuthin, but it's purty fishy, insofar as the mandateless Bush admin is concerned. Not only that, but think of all the superstionist rabble who chose 9-1-1 for their numbers on the 9/11 drawing. Coincidence? They all won. Spirits move in the most mysterious of ways. Why not Kansas' drawing or North Carolina? But it was New York.

My Skepticism leads me to think this is too coincidental. Gods and spirits be damned, the outcome of such a marginally profitable (pick three) apparition is good for spirit-thought and superstitious rumor for years. While we skeptics haggle over the unlikelihood of any kind of meaning, those who won and spread the fable make the news and we are further marginalized.

9-1-1 showing up on 9/11 a year after is a good thing for those who wish to control minds.

Ha ha ha ha. I'm psycho. But dear Lord, this is further proof that god loves America.

I prefer to believe that the subconscious force of everyone's will (going around all "9/11-9/11-9/11" all day) caused trading to finish and the little lottery balls to fall as they did. My irrational superstition of choice allows me to believe in the untapped powers of the human mind, which will someday allow me to overcome the diabolical forces of gravity which have held me back for so long.

Anyway, does anybody know how many people played that number? I'm sure it was quite many, and since each winner typically gets paid some $500 for that type of game, I'm sure it was a rather large payout from the coffers of the state.

If just 100,000 people played that number, total payout would be $50,000,000.

"Too coincidental" That's an amusing concept. My skepticism leads me to believe that mysterious forces aren't trying to send us a message through lottery balls.

Taken in a large enough context, everything that happens is essentially impossible. Consider the actual probability of you existing at all. Millions of your ancestors had to escape death from countless causes through the ages.

I argued this all morning with a coworker. For some reason, she was convinced, and still is, that this was a message from God.

I told her the odds of that were pretty slim. I mean, what is God trying to say, exactly? "Sorry I didn't stop the towers from falling..... here's some magic ping pong balls."

There's about as much logic to that as reasoning that crop circles are the product of alien intelligence. Yeah, right.... aliens have nothing better to do than sit around drawing "purty pitchers" in a cornfield and sticking probes up the anal passages of humans.

A similar thing happened here a couple months ago, where the Pick 3 Lottery was the same as the current date. Mind you, it wasn't a significant day in any regard, so it wasn't given a second thought. Just because something did happen on 9-11, it doesn't mean anything.

Apparently, the lotteries don't like it when the dates and lottery numbers are identical, as people tend to just play the current date... and pay-offs are usually larger on those kind of days.

Douglas Adams once posed a rationale in one of his books that the universe has absolutely no population. The argument was that since the universe is infinite, and there are only a finite number of populated worlds, then there must be an infinite number of unpopulated worlds. Therefore, the ratio of populated worlds to unpopulated worlds being (x/infinity) gives a sum as close to nothing as can be rationally established.

Obviously, much like the famous Achilles and the Tortoise concept, this idea in theory is blatantly untrue, (or, as Adams put it, "This is all, of course, completely impossible") but the same logic can still apply in one's mentality to coincidences like this lottery ticket.

There are a finite number of possible coincidences that actually came into play yesterday against an infinite number of possible coincidences that didn't. The ratio of a coincidence like the lottery ticket being 911 is merely considered interesting because none of the unsuccessful possible coincidences are identified (they can't be, obviously, having never happened.)

In other words, this is just that, a coincidence. The only reason that a random number generator produced 911 on 9/11 is considered "interesting" is because a random number generator producing any other number isn't. QED.

The idea that some "cosmic force" has mandated this is merely a refusal to observe the same "cosmic force" as having mandated the infinite number of things that happened today that aren't considered relevant in any way. To actually compare the ratio of interesting things against the infinite number of uninteresting things would produce a result so close to nothing that any organic entity would have to conclude that nothing interesting ever happens, ever.

I'm just cynical enough to suggest a set-up. And anyways, the numbers 911 have been so stamped and branded into our consciousness anymore that we're apt to notice it anywhere and attach meaning to it, even where there is no meaning to be had. My coworkers today were talking about how they would refuse to fly in an airplane on Friday the 13th (heads up, that's tomorrow)....anything bad that happens to them tomorrow, no matter how large or how trivial, they will probably attribute it to the fact that its Friday the 13th. Any other day when that large or small catastrophe occured, it would be just another day, but Friday the 13th is special....so it is with September 11th. We are all finding meaning where there is none.

My feeble attempt at the math: The probability that the lottery will be any date is the number of outcomes that are dates divided by the total number of lottery outcomes. Someone said that the outcomes won't have a leading or ending zero (is that true - couldn't find this documented on the NY lotto webpage). Then there's 1000 outcomes.

The number that are dates: There are 365 days, and the ones that have a two digit month and day are out. This disqualifies Oct 10-31, Nov 10-31, and Dec 10-31. So there's 301 days left. This results in a 301/1000 = 30% chance that the number picked will be a date.

**today's**date. Laws of conditional probability state: P(lottery is today's date) = P(lottery is a date AND date is today) = P(date is today | lottery is a date) * P(lottery is a date). We already computed P(lottery is a date). The prob that a given date is today is 1/365. Therefore, the probability that the lottery pick is today's date ends up being .000825, or a one in 1213 chance.posted by kelperoni at 12:51 PM on September 12, 2002

Thanks for those who did the math, and showed my estimate to be roughly correct. I always forget the exact equations to use for given situations.

jenn: as I said, I allowed for a "subset that fit the 3-digit format", which without figuring I estimated at from 250 to 300 days of the year. I think that was close enough. Accumulate a 1:1200 chance across that many dates, and you get a little less than one-quarter chance that sometime during a given year there will be a match. If you allow a four-year window, the probability rises to 1:1 that there will at some point be a match. So this game probably sees one roughly every four years, though each individual daily game remains at around a 1:1200 chance. Most of them simply go unnoticed, which leaves people freaking out when it does get noticed as some kind of 1-in-a-million coincidence, which it certainly isn't. The chance for ANY day is never

eas98: to answer your question, it looks like there were 15000 winners of some type in the numbers game, which is about 4-8 times the usual; the last time it was this big was 8/24, when the game drew 222. Usually about 500-1000 winners guess all three numbers; yesterday, over 5000 did. So, a little more expensive for them than usual, but not outside of existing extremes, either.

There are no odds to what day it is to factor because the day is a constant. There was a 100% chance that yesterday was going to be September 11, not a 1/356 chance. What you were calculating would be the equivalent of the odds of randomly selecting a date AND randomly selecting a number and the odds they match. And even so, given the double-date possibilities, certain results will therefore have different odds, much as how there are different odds for dice roll outcomes because of multiple addition combinations.

These figures are under the assumption of a "neutral condition environment." In other words, there is of course a microscopic probability that some events could actually affect the probability of outcome, anywhere the wind blowing a certain ball in the chamber to the insanely low probability that the earth will suddenly change orbit and alter the actual time thus preventing it from actually being September 11th. These are all factors that are assumed so insignificant that they are not addressed as possible, using the probability theory I said in my previous post. Your Gambler's Fallacy comes in the form of the belief that in some possible way yesterday could not have been September 11th.

The randomizer has no knowledge of the date, which in the real-life case is a constant. There was no probabilty that yesterday wasn't 9/11, the day being 9/11 was already happening at the time the drawing was made. It is a given the date is 911, the only odds we are calculating are if the number drawn that day is 911, of which the odds are 1 in 1000, no more, no less.

The difference in examples made easier: flipping two coins. Your math was like flipping two coins at the same time and getting the odds that a heads comes up... in that case the odds are 75% (25% chance of 2H + 50% chance of 1H/1T.) The lottery's equivalent was that one coin has already been flipped, and came up heads. Now you are calculating the odds that the next flip will match the previous... in this case, you are simply determining the odds that this flip will match the previously established constant: the odds are now 50% the coin will come up heads, i.e. matching the last flip.

The probability that the lottery number will be today's date is zero

The fact that some numbers could represent multiple dates (105 could be either 1/05 or 10/5), while true, is not relevant for the calculations, since for each date that can be represented as a three-digit number, there is only one such three-digit number, which means that the odds for that day are still 1 in 1000. So it's 1 in 1000 for the 301 dates that can be represented as there-digit numbers, and 0 in 1000 for the 64 days that can't. Average it together and you should get the same result kelperoni got, just from a different angle.

*on dates that can't be lottery numbers.*So on average, the probability that the lottery number is today's date (for a randomly-chosen date) is substantially less than 1 in 1000. Kelperoni's 1 in 1213 sounds about right if you allow zero to be used for dates that would otherwise be two digits. (I personally would disallow this, since dates do not include leading zeroes, but undoubtedly people do play dates like 1/5 as "105," so it seems better to go with what people actually play.)The fact that some numbers could represent multiple dates (105 could be either 1/05 or 10/5), while true, is not relevant for the calculations, since for each date that can be represented as a three-digit number, there is only one such three-digit number, which means that the odds for that day are still 1 in 1000.

XQUZYPHYR - we are actually trying to answer different questions. You're focusing on the probability of drawing a 911 on 9/11, I computed the probability of drawing the date on

You're also right about the doubles thing, I didn't even think about that. So I guess you're more right than I am...

*any*day in the year. So we're both right, for the question that we are answering.You're also right about the doubles thing, I didn't even think about that. So I guess you're more right than I am...

This from here

And let me juxtapose to that the utter spookywookiness of the New York Lottery number being 9-1-1 yesterday. If that doesn't make you stop and think, you need to SERVICE ENGINE SOON. Today's Daily News piece on this "eerie coincidence"--boy, they can say that again--quoted some regular guy saying, "I think somebody's trying to tell us to look on the bright side." They didn't cap the S, but still, isn't that a nice thought to leave everybody with?

The paper said today this was the first time that a date was drawn on said date in three years. Was this one of those drawings that they show on television? I would LOVE, LOVE to see that tape. WOW. The cute "ball girl" must have freaked out or something.

Paris: I'm not sure the ball girls on state lotteries are required to be cute. Or, for that matter, girls.

Here's a link that breaks down the probability.
