1. The problem statement, all variables and given/known data At a conference of 5 powers,each deligation consists of 3 members. If each delegation sits together, with the leader in the middle, in how many ways ca the members be arranged at a round table? 2. Relevant equations No. of ways of arranging n objects around a circle=(n-1)! P(n,r)=n!/(n-r)! 3. The attempt at a solution I understand that 15 people go around the table => no. of ways to arrange=14! But again in their different delgations,each can be arranged 2!/(2-2)!=2ways => There are 2(15) ways to arrange within the delegations .'. there are 14!(30) ways IS THIS CORRECT?
