But what the normal distribution is, it's a continuous probability density function. So it can tell us, what's the probability of being 2.183 feet away? Which obviously can only happen if we're kind of taking infinitely small steps every time. But that's what its use is. It happens kind of when you start taking an infinite number of steps. But it can approximate the discrete. And the way I approximate it is I say, oh, what's the probability of being within a foot of that?
