Mean of a probability distribution function
WebA CDF function, such as F (x), is the integral of the PDF f (x) up to x. That is, the probability of getting a value x or smaller P (Y <= x) = F (x). So if you want to find the probability of rain between 1.9 < Y < 2.1 you can use F (2.1) - F (1.9), which is equal to integrating f (x) from x = 1.9 to 2.1.
