[countable] A game in which people buy tickets with numbers, and those who win get prizes. A lottery can be run by a government or by private groups. Prizes may be cash or goods. Some governments outlaw lotteries; others endorse them and regulate them. The casting of lots to decide issues has a long history (see, for example, the Bible and ancient Roman records). The first recorded public lotteries to offer tickets with a money prize were held in the Low Countries in the 15th century. They were used to raise funds for town fortifications and to help the poor. Lotteries were also popular in colonial America and played a major role in financing both private and public ventures, including roads, canals, bridges, schools, and churches.
A lottery must have three things to be legal: consideration, chance, and a prize. Consideration is the price of a ticket, and prize can mean anything from money to a new car. The chances of winning are the odds, which can be changed by increasing or decreasing the number of balls in a pool, or changing the way the numbers are drawn. Lotteries are regulated by state laws, and federal statutes prohibit the sale of tickets via mail or over the phone.
Lotteries usually win broad support because the proceeds are earmarked for a specific public good, such as education. However, studies have shown that the popularity of a lottery is not related to a state’s actual fiscal health, and that it is primarily based on the psychological concept that “Hey, it could be me.” This sense of hope, even when improbable, is what makes the lottery attractive.
