The probability is given by the area under that curve. It would be given by this area. And for those of you all who know calculus, if P of x is our probability density function, it doesn't have to be a normal distribution, although it almost always, well, it often is a normal distribution. The way you actually figure out the probability of, let's say, between 4.5 and 5.5, what is the probability, this is whatever, the odds of me getting between 4.5 and 5.5 inches of rain tomorrow. It'll actually be the integral from 4.5 to 5.5 of this probability density function, or of this probability density function, dx. So that's just the area of the curve. For those of you who don't know calculus yet, I encourage you to watch that playlist.
