<prompt> Human: So there are a lot of people here who seem to have won the lottery. Which got me thinking, assuming a jackpot-style not scratch-off lottery ticket is 2, when would it make sense to buy a ticket? How much would the jackpot need to be?And would it ever make sense to buy one ticket each week? Assume the 2 a week wont be otherwise be missed.  <response>: The odds are so very, very remote you should just consider it money spent and not an investment. Treat it like any other form of gambling: do it for entertainment value, not to earn a profit.
