Needed part D only please.

1. Suppose your waiting time for the campus shuttle in the morning is uniformly distributed on [0, 8],
but the waiting time in the evening is uniformly distributed on [0, 15)], independent of the morning
time.
(a) If you take the shuttle every morning and evening for a week, what is your total expected
waiting time?
(b) What is the variance of your total waiting time?
(c) What are the expected value and variance of the difference between the morning and evening
