To determine the winners of a lottery, the winning numbers or symbols are selected in a drawing. This drawing may be done by some mechanical means, such as shaking or tossing, or by computer. The computer-based method is used more frequently because it allows for a large number of tickets to be analyzed and the odds to be computed quickly. The number of tickets sold and the likelihood of winning are computed by using a formula called the factorial.
