A student council consists of 15 students.(a) How many ways can a committee of eight be selected from the membership of the council?As in Example 9.5.4, since a committee chosen from the members of the council is a subset of the council, the number of ways to select the committee is 6435(b) Two council members have the same major and are not permitted to serve together on a committee. How many ways can a committee of eight be selected from the membership of the council?As in Example 9.5.6, let A and B be the two council members who have the same major.The number of ways to select a committee of eight that contains A and not B is 1716The number of ways to select a committee of eight that contains B and not A is 1287The number of ways to select a committee of eight that contains neither A nor B is 3003XThe total number of committees of eight that can be selected from the membership of the council is the sumThus, the answer is 3003x(d) Suppose the council contains eight men and seven women.(c) Two council members insist on serving on committees together.

So, thetotal number of committees of eight that can be selected from the membership of the council is(i)Xof the number of committees with A and not B, B and not A, and neither A nor B.(ii) How many committees of six contain at least one woman?The number of committees of six that contain at least one woman isHow many committees of six contain three men and three women?As in Example 9.5.7a, think of forming a committee as a two-step process, where step 1 is to choose the men and step 2 is to choose the women. The number of ways to perform step 1 is, and the number of ways to perform step 2 isThe number of committees of six with three men and three women is the productof the number of ways to perform steps 1 and 2.
