A lottery is a game of chance in which winners are selected through a random drawing.

Although the lottery is a popular form of gambling, it is not rational according to decision models based on expected value maximization. This is because the expected value of a ticket is less than the cost, and therefore a person maximizing expected utility would not purchase it.

Other factors may also motivate people to buy lottery tickets, such as social pressure and the desire to improve their financial situation.

A common mistake when selecting lottery numbers is to focus on the most recent results. This can backfire, as previous winners can affect the odds of future draws.
