All of that squared. That's where this calculation came from. And so I told you in the last one, I mean, this just tells you, this right here just tells me this value up here. 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.
