receive is brand new, it will break down with probability 0.08. If the car is nearly one year old, it
will break down with probability 0.09. And if the car is old, it will break down with probability
0.5. The probability that the rental company gives you a new car, a nearly one year old car, and
an old car is 0.5, 0.25, and 0.25, respectively. What is the probability that your car breaks down
