A lottery is an arrangement in which prizes are awarded through a process that relies entirely on chance. It is a low-odds game, and the prize amounts are typically less than the cost of the tickets. This means that a lottery is not necessarily profitable if most people purchase tickets, but it may provide an opportunity for some to experience a thrill or indulge in a fantasy of becoming wealthy without pouring in decades of effort. Lotteries can be analyzed using decision models based on expected value maximization, and they can also be characterized by risk-seeking behavior.

There are many different types of lotteries, including financial ones in which participants bet a small amount for the chance to win a large sum of money. These can be run by governments and private companies, and are a popular form of gambling. There are also non-profit lotteries that award grants to individuals or groups. These can be used for purposes such as distributing scholarships or determining who receives scarce medical treatment.
