Answer by jim_thompson5910(35256) (Show Source):
You can put this solution on YOUR website! C(n,r) = (n!)/(r!(n-r)!)
C(5,3) = (5!)/(3!*(5-3)!)
C(5,3) = (5!)/(3!*2!)
C(5,3) = (5*4*3!)/(3!*2!)
C(5,3) = (5*4)/(2!)
C(5,3) = (5*4)/(2*1)
C(5,3) = (20)/(2)
C(5,3) = 10
So there are 10 ways (assuming order doesn't matter)
