4. At a small branch of the Mid West bank the manager has a staff of 12, consisting of five men
and seven women including a Mr Brown and a Mrs Green. The manager receives a letter from
head office saying that four of his staff are to be made redundant. In the interests of fairness the
manager selects the four staff at random.
a) What is the probability that both Mr Brown and Mrs Green will be made redundant?
