But they're telling us that the cards can be sorted however the player chooses. So order doesn't matter. So we're over-counting. We're counting all of the different ways that the same number of cards can be arranged. So in order to, I guess, not over-count, we have to divide this by the way 9 cards can be rearranged. So how many ways can 9 cards be rearranged? If I have 9 cards, and I'm going to pick one of 9 to be in the first slot, well, that means I have 9 ways to put something in the first slot.
