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. And so we're just, hopefully I didn't confuse you, but you know, if I did, you can go back to this formula for the binomial coefficient. But it's good to have the intuition. And then, well, once we're at this point, we can just calculate this.
