So there's 364 possibilities out of 365. So if you had two people, the probability that no one is born on the same birthday, this is just 1, is just going to be equal to 364 over 365, right? Now, what happens if we had three people? So first of all, the first person could be born on any day, then the second person could be born on 364 possible days out of 365, and then the third person, what's the probability that this third person isn't born on either of these people's birthdays? So two days are taken up, so the probability is 363 over 365. So this is equal to, you multiply them out, you get 365 times 360. Actually, I should rewrite this one.
