For a randomly selected county in the United States, let X represent the proportion of adults over age 65 who are employed, or the elderly employment rate. Then, X is restricted to a value between zero and one. Suppose that the cumulative distribution function (CDF) for X is given by F(x) = 3x^2-2x^3 for 0<=x<=1 Find the probability that the elderly employment rate is at least 0.6 (60%). What is the probability that the elderly employme
