The first rule of a lottery is that the numbers are chosen randomly. The numbers are drawn from a pool of numbers from 1 to 70. Some lotteries use a computer to determine the numbers, but most of them have a human draw.
Many lotteries are also based on probability theory, and each winner is awarded a random chance of winning. The odds of winning are calculated by multiplying the probability of any given combination by the number of possible combinations, which is called a factorial.
One of the most common ways to determine the odds of winning a lottery is to compare it with other events. For example, the odds of winning a car are one in 18,033; of being struck by lightning, one in 4,332,817; of being attacked by a shark, one in 2.1 million; and so on.
