- The probability of not buying a used vehicle is 1 - 0.5 = 0.5, making statement A true.- If you buy a new car, given the condition that you cannot go home with more than one vehicle, you indeed will not buy a used car, making statement B true.- Purchasing a new car and purchasing a used car are disjoint (mutually exclusive) events because the condition states you will not go home with more than one vehicle, making statement C true.
