Question 131177: Thanks in advance for your help.
In how many different ways can three students be seated in a row of 5 desks? Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! This is a permutation question because we care about which way they are arranged.
nPr= n!/(n-r)!
5P3=5!/(5-3)!
=5*4*3*2/2
=5*4*3
=60
