Most people belong to some type of group -- families, classes at school, and clubs or organizations, for example. Often groups reach decisions through a voting procedure. Cooperation among the members of a group is required, and groups need rules and leaders to get things done. It is important for each person involved in a group to have a voice in deciding the rules and choosing the leaders. This is accomplished by voting, with members agreeing to follow the choice of the majority, which is more than half of the voting members. The same is true for choosing the leaders who will govern cities, towns, states, and our country.
