That was this term right over here. I'm doing a case that is a little bit longer, where k is a slightly larger number, because this right over here is 5 minus 2. That is this one over here. Just not to confuse you, let me write it like this. You'll have n spots for that first head, n minus 1 spots for that second head. Then you keep going and you're going to have a total of these k things you're multiplying. That last one is going to have n minus k minus 1 possibilities.
