So to have exactly 2 left, so it's 2 minus the mean. So the mean is 5. Divided by the standard deviation, divided by 1.581. 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.
