# Math Help - possble seating plans

1. ## possble seating plans

Seems simple one,but I have conflict on this with one of my friend.

There are 5 chairs in a row, and three people. In how many ways can
you place the people on the chairs? (each person must occupy exactly
one chair, so that two chairs will remain free).

So if by p(5,3), you mean $_3P_5=\frac{5!}{(5-3)!}$, your answer is correct.
