Suppose that the time (in hours) required to repair a machine is an exponentially distributed random variable with parameter A = 0.3. What is (a) the probability that a repair takes less than 5 hours? (b) the conditional probability that a repair takes at least 6 hours, given that it takes more than 4 hours?
