A lottery is a procedure for distributing something (usually money or prizes) among a group of people by lot or chance. In the most familiar form of lottery, tickets are sold for a chance to win a prize. The winners are selected by drawing lots. The prize may be money or goods. The word is probably of Germanic origin, influenced by the Old English and Middle Dutch words for “lot” or “a share,” and may be related to a Frankish root that means “to divide.”
A common form of the lottery is one in which the prize amount is a fixed percentage of total receipts. This format has the advantage of avoiding the risk to the organizer of losing money by selling insufficient tickets. However, it has the disadvantage of lowering the average winnings.
In the 15th century, the Low Countries held public lotteries to raise funds for town fortifications and to help the poor. Lotteries also played a major role in colonial America, funding roads, canals, libraries, churches, colleges, and other public works.
The main argument in favor of lotteries is that state governments need revenue, and a lottery is the best way to get it. In addition to that argument, there is the belief that gambling is inevitable anyway, so a government might as well make money from it rather than regulate or ban it. Nevertheless, state officials recognize that there is the danger of compulsive lottery playing and have made some efforts to counter it, such as running hotlines for addicts.
