A surprising result that appears in many Elementary discussions on probability is called the birthday problem. The question simply stated is that if we poll a certain number of people, what is the probability that at least two of those people were born on the same day of the year? To solve this problem, use the formula for computing the probability of a complement of a event. It is clear that P(duplication of some birthdays)=1-P(n I duplications). Assume that there are 4 people. Find the probability that at least 2 of the 4 people were born on the same day of the year. Do not consider February 29th in leap year when finding the probability.
