This is equal to 360. So this is, each of these, this is one permutation. This is another permutation, and if we keep doing it, we would count up to 360. But we learned in combinations, when we're thinking about combinations, let me write combinations. So if we're saying N choose K, or how many combinations are there, if we take K things, and we just want to figure out how many combinations, sorry, if we start with N, if we have a pool of N things, and we want to say how many combinations of K things are there, then we would count these as the same combination. So what we really want to do is we want to take the number of permutations there are, we want to take the number of permutations there are, which is equal to N factorial over N minus K factorial, over N minus K factorial, and we want to divide by the number of ways that you could arrange four people. Once again, and this takes, I remember the first time I learned it, it took my brain a little while, so if it's taking a little while to think about it, not a big deal.
