That's essentially just saying, how many permutations, can I, you know, how many ways can I pick three things out of eight? And that's essentially saying, well, before I pick anything, I can pick one of eight. Then I have seven left to pick from for the second spot. And then I have six left to pick for the third spot. And so that's essentially the number of permutations. But since we don't care, you know, if we picked it, what order we pick them in, we need to divide by the number of ways we can rearrange three things. And that's where the 3 factorial comes from.
