At a small branch of the midwest bank the manager has a staff of 12, consisting of 5 men and 7 women including a Mr Brown and Mrs Green. The manager recieves a letter from head office saying that 4 of his staff are to be made redundant. In the interests of fairness the manger decides to select 4 staff at random.

Well there are 4 staff to be chosen, 2 are Mr Brown and Mrs Green, so there are 2 more to chose, from 10 members of staff.

So It's 10C2 = 45
