4. X1, X2, X3, X., Xs are independent random variables with a common distribution. That distribution is the Normal distribution. The mean is 28.2 and the standard deviation is 3.5 (a) Calculate the probability exactly four of these random variables have a value greater than 32 (b) Y = X, - Xz. Calculate P(5 <Y <10).
