A bank operates a drive-up facility and a walk-up window. On a randomly selected day, let X be the proportion of time the drive-up facility is in use, and Y be the proportion of time the walk-up window is in use. The joint support is Ω = {0 ≤ X ≤ 1, 0 ≤ Y ≤ 1}, and the joint pdf is given by

f (x, y) = (6/5)*(x + y^(2) ) where (x, y) ∈ Ω

Find the probability that neither facility is busy more than 1/4 of the time.

Willow Brook National Bank operates a drive-up teller window that allows customers to complete bank transactions without getting out of their cars. On weekday mornings, arrivals to the drive-up teller window occur at random, with an arrival rate of 24 customers per hour or 0.4 customers per minute. Also assume that the service times for the drive-up teller follow an exponential probability distribution with a service rate of 36 customers per hour, or 0.6 customers per minute. Determine the probabilities...
