And this kind of clarifies a little bit what's going on here a little bit better. Because what's this? x minus sigma is the distance between whatever point we want to find, let's say we're here, x minus mu, mu is the mean, so that's here, so that's this distance. And this is the standard deviation, which is this distance. So this in here tells me how many standard deviations I am away from the mean, and that's actually called the standard z-score I talked about in the other video. And then we square that, and then we take this to the minus 1 half, well, let me rewrite that. If I were to write e to the minus 1 half times a, that's the same thing as e to the a to the minus 1 half power, right?
