What is a Lottery?

Lottery is a form of gambling in which a prize, such as money or goods, is awarded to the winner or winners of a random drawing. The word lottery is derived from the Dutch noun lot, which means “fate.” Lottery has long been a popular way to raise funds for public usages such as schools, hospitals, canals, roads, and bridges. In colonial America, it played a major role in financing public and private projects.

To be considered a lottery, there are several requirements that must be met: a mechanism for collecting money as stakes; a system for shuffling and selecting winning numbers; rules governing frequency and size of prizes; and a method for allocating the prize money to participants. Many modern lotteries are operated by computer systems that record the identities and amounts of money bet, and then select winning numbers from a pool of all bettors. In addition, the cost of organizing and promoting the lottery must be deducted from the total prize money.

The Educated Fool

This type of lottery player, who distills all the complex information about probability and expected value into a one-number summary, is a rare creature and a treat for gambling anthropologists like us. However, the educated fool also does what all foolish people do: mistakes partial truth for total wisdom.
