This is all the same set of three people if we don't care which chair they're sitting in. This would also be the same set of three people. And so this question, if I have six people sitting in three chairs, how many ways can I choose three people out of the six where I don't care which chair they sit on? And I encourage you to pause the video and try to think of what that number would actually be. Well, a big clue was, when we essentially wrote all of the permutations where we've picked a group of three people, we see that there's six ways of arranging the three people. And you pick a certain group of three people that turned into six permutations. And so if all you want to do is care about, well, how many different ways are there to choose three from the six, you would take your whole permutations, you would take your number of permutations, and then you would divide it by the number of ways to arrange three people.
