suppose that the wait time at the bank is uniformly distributed in the interval 4-min-8min find the probability that a randomly selected customer has to wait longer than 6.5 minutes
here the inter arrival time t~unif(4,8)
the for the prob. that there will be watting > 6.5 mint = intgral(from 6.5 to 8 mint of 1/(8-4) ) = .0375
