Well, you might immediately say, well, that's going to be five factorial which is going to be equal to five times four times three times two times one. Five times four is 20. 20 times three is 60. And then 60 times two is 120. And then 120 times one is equal to 120. And once again, that makes a lot of sense. There's five different, if no one sat down, there's five different possibilities for seat number one.
