So this is just going to be, this is going to be equal to one out of the 32 equally likely possibilities. Now, for this case, to kind of think in terms of kind of the binomial coefficients and combinatorics and all of that, it's much easier to just reason through it. But just so we can think in those terms, it'll be more useful as we go into higher values for our random variable. And it's also, this is all a buildup for the binomial distribution, so you get a sense of where the name comes from. Let's write it in those terms. So this one, this one, this one right over here, the one way to think about that in combinatorics is that you had five flips and you're choosing zero of them to be heads. Five flips and you're choosing zero of them to be heads.
