The amount of milk (in thousands of gallons) that a dairy sells each week is a random variable X with the density function f (x) = 4(x - 1)3, 1 ≤ x ≤ 2. (See Fig. 4.)

(a) What is the likelihood that the dairy will sell more than 1500 gallons?

(b) What is the average amount of milk that the dairy sells each week?
