Suppose there are 5 students in a class. What is the probability of having exactly 3 students who have the same birthday? I am thinking I should have $365 \times 365 \times 364 \times 363 \times 362$ and then divide all of it by 5. But it doesn't feel right. What should I do to find out the probability?
