And then, and you could probably guess what we're going to get for x equals five, because having five heads means you have zero tails, and there's only going to be one possibility out of the 32 with zero tails, or that have all heads. Let's write that down. So the probability that a random variable x is equal to five, so we have all five heads. And you could say this is five, and we're choosing five of them to be heads out of the 32 equally likely possibilities. Well, five choose five, that's going to be, actually let me just write it here, since I've done it for all the other ones. Five choose five is five factorial over five factorial times five minus five factorial. Well, this right over here is zero factorial, which is equal to one, and so this whole thing simplifies to one.
