Question 412876: Please help me solve this problem: You have 5 books. In how many different orders can you read three of the 5 books? Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! When order is important it's a permutation
nPr=the number of ways n things can be arranged r at a time.=n!/(n-r)!
5!/2!=5*4*3=60 ways
