Suppose the proportion x of surface area in a randomly selected quadrant that is covered by a certain plant has a standard beta distribution with aplha = 4 and beta = 3:

E(X) = 0.5714

V(X) = 0.0306

a) Compute P(X less than or equal to 0.4) estimate to four decimal places

b) Compute P( 0.4 less than or equal to X less than or equal to 0.8) estimate to four decimal places

c) What is the expected proportion region not covered by the plant?
