Suppose that X is the length of time (in minutes) that a customer queues in a bank. The probability density function of X is given by (36–x²) 144 0 < x < 6, fx(x) = {, otherwise. find E(X), the expected value of Xand interpret thisTOsult. Fina Fx(#), the cumulative distribution function of X. Given that a customer has been queuing for 3 minutes, find the con- ditional probability that this customer will be queuing for at least 5 minutes in total.
