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? 330, all the way down to 336, right? That'll actually be 30 terms divided by 365 to the 30th power, and you could just type this into your calculator right now, it'll take you a little time to type in 30 numbers. And you'll get the probability that no one shares the same birthday with anyone else.
