I could have exactly three people have the same birthday. I could have exactly 29 people have the same birthday. All of these make this true. So do I add the probability of each of those circumstances and then add them up and then that becomes really hard and then I would have to say, OK, whose birthdays am I comparing and I would have to do combinations. It becomes a really difficult problem. Unless you make kind of one very simplifying, I would say, take on the problem. This is the opposite of, let me draw the probability space.
