    [SOLVED] Stats

    The car seller experience is such that the probability distribution over the customers gender and type of car is as follows:

    Man Woman
    Sport 0.1 0. 06
    Family 0.2 0. 03
    No car 0.5 0.11


    What is the probability (based on his experience) that he will sell the family type of car, once he sees a man entering his store?

    Pr(sells family car | man) = Pr( sells family car AND man)/Pr(Man) = 0.2/0.8 = 1/4.
