A lottery is a game in which numbers are drawn at random and the people who have those numbers on their tickets win prizes. Lotteries are commonly used in sports and in finance, where the prize money may be very large. They also have many other applications, such as determining the distribution of units in a subsidized housing block or kindergarten placements at a reputable public school. For many individuals, the entertainment value and other non-monetary benefits of playing a lottery outweigh the disutility of losing money, making it a rational decision for them to participate in one.

State governments promote lotteries as a way to raise revenue for things like education. But how much the money raised actually helps, and whether that’s worth the price of so many people losing their money, is a complex question.

Americans spend more than $100 billion on lotteries a year, making it the country’s most popular form of gambling. So why do so many people keep buying these tickets despite the odds of winning being so low? And what does it say about the way we think about money and risk?
