As a result of the way lottery mathematics works, it is impossible to explain the purchase of a lottery ticket by decision models based on expected value maximization. This is because the price of the ticket is higher than the expected gain, which means that a person who is maximizing expected value would not buy the ticket.

However, the purchase of a lottery ticket may still be a rational decision if the entertainment value or other non-monetary benefit from playing exceeds the disutility of a monetary loss. These benefits may not be available in other contexts, but they are typically sufficient to make the purchase a rational one.

Many modern lotteries have a computer system that records the number of tickets and their selected numbers, enabling people to play without having to write down their selected numbers. There are also some lottery games where you can allow the computer to randomly pick a set of numbers for you.
