    I'm studying... S1 statistics

    I'm interested in... The members of a wine tasting club are married couples. For any married couple in the club, the probability that the husband is retired is 0.7 and the probability that the wife is retired is 0.4. Given that the wife is retired, the probability that the husband is retired is 0.8.
    For a randomly chosen married couple who are members of the club, find the probability that
    A) both of them are retired,
    B) only one of them is retired,
    C) neither of them is retired.
    Two married couples are chosen at random.
    D) find the probability that only one of the two husbands and only one of the two wives is retired.

    I'm really confused with this entire question...?
