7. An insurance company sells two types of policy for car insurances, which we call type A and type B. The clients are then divided into two categories: over 50 years of age and under 50 years of age. The company knows that: • 40% of the clients who purchased policy A is over 50. • 80% of the clients who purchased policy B is under 50. • 26% of the clients are over 50. A client over 50 is chosen. Find the probability that the client purchased policy A. [Hint: to solve this problem, proceed as follows. Draw a tree diagram and set P(type A) = Find an equation for x and solve it. You then will have all the data to answer the question.] = x.
