And I assume that the probability, if I want to know this exact probability, it's the area of this. And if I just take one line, the area is 0. So to be exactly 2 feet away using the, remember, I mean, in this case, you can only be 2 feet away because we're taking very exact steps. 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.
