suppose that 15% of the families in a certain community have no car, 20% have 1 car, 35% have 2, and 30% have 3. Suppose, furt hat in each family, each car is equally likely (independently) to be a foreign or a domestic car. Let F be the number of foreign cars nd D the number of domestic cars in a family. he random variable denoting the number of cars in a family and the random variable denoting the number of foreign cars are Eelect one: а. mutually exclusive so one has to use the union rule for mutually exclusive events to calculate the joint probability tha F=1 and D=1.
