Or how many ways can I pick three of these people to sit in chairs? And it doesn't matter the order that I pick them in, right? It doesn't matter if I say the people that are going to get in the car are going to be people one, two, and three. Or if I say three, two, and one. Or if I say two, three, and one. Those are all the same combination, right? So similarly, if I'm just picking flips, and I have to say, OK, three of these flips are going to get into the heads car, or are going to sit on, you know, heads is like they're people sitting down.
