WebFirst, we find the cumulative distribution function of Y: Having shown that the cumulative distribution function of Y is: F Y ( y) = y for 0 < y < 1, we now just need to differentiate F ( y) to get the probability density function f ( y). Doing so, we get: f Y ( y) = F Y ′ ( y) = 1 for 0 < y < 1. That is, Y is a U ( 0, 1) random variable.

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.
