8 Let X have a uniform distribution on the interval [A,B]. compute V(X)
9 Let X have a standard gamma distribution with α=7 α=7. Compute P(X<4 or X>6)
10 Let X = the time between two successive arrivals at the drive –up window of a bank. If X has a exponential distribution with h=1 ( which is identical to a standard gamma distribution with a=1). Compute the standard deviation of the time between successive arrivals
