Seat people permutation or combination
WebSo the total number of permutations of people that can sit on the chair is 5* (5-1)* (5-2)=5*4*3=60. We can make a general formula based on this logic. For n people sitting on k chairs, the number of possibilities is equal to n* (n-1)* (n-2)*...1 divided by the number of extra ways if we had enough people per chair. WebIn this case order of choosing the people matters so it will be a permutation. The first person is the president , the 2nd is the Vice President and the 3rd is the Secretary so it matters if the person is 1st,2nd or 3rd. If they were being selected for the same positions then order would not matter and it should be a combination.
