WebTo find this probability we simply use the CDF of our random variable. Because the CDF tells us the odd of measuring a value or anything lower than that value, to find the likelihood of measuring between two values, x1and x2(where x1> x2), we simply have to take the value of the CDF at x1and subtract from it the value of the CDF at x2.
