The length of time necessary to tune up a car is exponentially distributed with a mean
Chapter 6, Problem 6.56(choose chapter or problem)
The length of time necessary to tune up a car is exponentially distributed with a mean of .5 hour. If two cars are waiting for a tune-up and the service times are independent, what is the probability that the total time for the two tune-ups will exceed 1.5 hours? [Hint: Recall the result of Example 6.12.]
