I occasionally buy a few lottery tickets when the jackpot is superhigh and thus the "expected value" of the ticket is near or over the $1 ticket price. Am I still wasting my money?I do this too, but: if you want to buy "a few" tickets you have to compute the expected value of the lot knowing that you can't win two jackpots. It's much more rare for the "average" payoff on two tickets to exceed $2.

Am I still wasting my money?Likewise, as ryanrs explains (why 1-2-3-4-5-6 is a lousy pick), you have to factor how many people are competing against you. If the number of competitors is high enough to expect 2+ winners, then the "expected value" drops very quickly.

Now I'm curious when the last time 1-2-3-4-5-6 won a lottery and how many people won ...At least with the national Powerball game, there are about 250 ways to pick six consecutive numbers: the red ball only goes to 39, and can be first, second, third, etc. in the sequence. There are 200 million combinations, so you expect one "consecutive" pick to win, on average, per million drawings. There are a hundred drawings per year, so the mean time between consecutive wins will be ten thousand years. I think that the Powerball game is not quite that old yet, so the most likely number of consecutive winning tickets in its history is zero.

There's an increasing tier level, and a few years back, they to had invent a new tier, Seven Star. To be a Seven Star means you have to lose a set amount to the casino every year ($500,000? I can't remember the amount anymore, but it was a LOT of money to be losing every year).Actually, Seven Star requires a handle of 500k. Someone who plays perfect strategy blackjack or baccarat could hit Seven Star with an expected loss of 10k or so.
