Question 551818: How many ways can five women and two men can be seated on a chair if only three seats?
Answer by jim_thompson5910(35256) (Show Source):
You can put this solution on YOUR website! There are 5+2 = 7 people total and P(7,3) = (7!)/(7-3)! = (7!)/(4!) = 5040/24 = 210 ways to seat all of them in 3 seats (assuming order matters).
If order doesn't matter, then there are C(7,3) = (P(7,3))/(3!) = 210/6 = 35 different ways to seat them.
