Suppose that the amount of time one spends in a bank is exponentially distributed with a mean of ten minutes, that is µ = 1/10. What is the probability that a customer will spend more than twenty-five minutes in the bank? What is the probability that a customer will spend more than 25 minutes in the bank given that she is still in the bank after 15 minutes?
