in a survey of a town 52% of residents on a car 34% of residents own a truck and 8%of residents own both a car and a truck.what is the conditional probability that a person who owns a car also own a truck?

Respuesta :

Let's say there are 100 people on this town. That means that 52 people own a car and 8 people own a car and A truck. So you divide 52 by 8 and get 0.15 which you multiply to 100 to get 15% so there is a 15% chance that. A person who owns a car in the town also owns a truck
