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. Well, what's this? This is 8 times 7 times 6 over 3 factorial is 3 times 2 times 1, so that's 6. So 6 cancels out, so it's 8 times 7.
