Lottery is a method of allocating prizes, especially money, by drawing lots. Its roots are in ancient times; the Old Testament instructed Moses to divide land among the people by lot. Roman emperors held lottery games to give away slaves and property, and many dinner parties in Renaissance Italy featured apophoreta, where guests placed wooden pieces with identifying symbols on them toward the end of the meal and were drawn for prizes that they carried home.

Lotteries provide an alternative source of funds for public projects that would otherwise be difficult to finance. While many people argue that gambling is a vice and should be taxed as such, others argue that lottery proceeds are far less harmful than sin taxes on alcohol and tobacco, and can be used to fund education, medical care, social services and other programs that might not be funded otherwise.

In general, the purchase of a lottery ticket cannot be accounted for by decision models based on expected value maximization, as lottery mathematics shows that the probability of winning is much greater than the cost of the ticket. However, more general models based on utility functions defined on things other than the lottery prize may be able to explain lottery purchases.

If you’re a serious lottery player, consider starting a lottery pool with some friends or family members. Choose the most dependable person to serve as your pool manager, who will be responsible for tracking all members, collecting money, purchasing tickets and selecting numbers. Clearly define the rules of your lottery pool, including how you’ll divide any winnings and whether to accept lump sum or annuity payments.
