So this, the x-axis here is the amount of rain. Where this is 0 inches, this is 1 inch, this is 2 inches, this is 3 inches, 4 inches. And then this is some height. Let's say it peaks out here at, I don't know, let's say this is 0.5. So the way to think about it, if you were to look at this and I were to ask you, what is the probability that y, because that's our random variable now, that y is exactly equal to 2 inches? That y is exactly equal to 2 inches. What's the probability of that happening?
