Actually, I should rewrite this one. Instead of saying this is 1, let me write this as, the numerator is 365 times 364 over 365 squared. Because I want you to see the pattern, right? Here the probability is 365 times 364 times 363 over 365 to the third power. And so in general, if you just kept doing this to 30, if I just kept this process for 30 people, so 30 people, the probability that no one shares the same birthday would be equal to 365 times 364 times 363. We'll have 30 terms up here, right? All the way down to what?
