Suppose we have 2 teams: A and B. Each team has 4 members. They are seated at a round table, and arrangements are considered the same when one can be obtained from the other by rotation. a) How many circular arrangements are possible for 8 people without any restriction? b) We want to arrange those 8 people around the table so that the teams alternate (means same team members cannot sit next to each other) How many different circular arrangements are possible with this restriction? HINT: In Figure below, arrangements (a) and (b) are considered identical, whereas (a) and (c) are two distinct arrangements..
