That's equal to, you can imagine you have nine cards to pick from. The first card you pick is going to be one of 36 cards, then the next one's going to be one of 35, then the next one's going to be one of 34, 33, 32, 31. We're going to do this nine times, 1, 2, 3, 4, 5, 6, 7, 8, and 9. So that would be the total number of hands if order mattered. But we know, and we've gone over this before, that we don't care about the order. All we care about the actual cards that are in there. So we're over counting here.
