The probabilities that a car will require repairs within the first year are 5% for compact cars, 7% for midsize cars, and 10% for SUVs. If a car is found to require repairs within the first year, what is the probability that it is a compact car, a midsize car, and an SUV? Please show all your work, first write the formulas you are using then plug in the given value. (4 points) 1B.
