Are people who constantly play the Lottery simply bad at math, desperate, or plain ole' addicts?

some people feel that the chance to win outweighs what the money it costs could buy them. 1 dollar, 1 diet coke. At best, a diet coke. at worst, a diet coke. Megamillion lotto. At worst, nothing. at best 200 million dollars? thats the logic. however, id rather play 1 dollar buy in poker tourneys
