So let's say at minus 20, the height is very low. At minus 5, well, let's say at minus 2, the height's a little bit better. The height's going to be someplace, it's going to be like right there. And so that gives me that value. But then to actually figure out the probability of that, what I do is I calculate the cumulative distribution function between, well, this is the value, the probability that you're less than that. So the area under the curve below that, which is very, very small. It's not 0.
