math specifically probabilty

You and your friend just rented a car for an 8,000 mile cross-country road trip. Your rental carmay be one of three different types: new (N), nearly one year old (O), and old (L). If the car youreceive is brand new, it will break down with probability 0.08. If the car is nearly one year old, itwill break down with probability 0.09. And if the car is old, it will break down with probability0.5. The probability that the rental company gives you a new car, a nearly one year old car, andan old car is 0.5, 0.25, and 0.25, respectively. What is the probability that your car breaks downon your road trip? Use a probability tree to support your answe
