Which simulation would work best to find the experimental probability that three people in a group of 22 were born in the same month?

There are 12 possible birth months, so each person’s simulated birth month should be chosen randomly from 1 to 12. Repeating this for 22 people lets you check whether any month was assigned to three people. Therefore, a random-number generator with numbers from 1 to 12 is the best simulation.
