Question 765458
If order matters, then...



n P r = (n!)/((n-r)!)


12 P 8 = (12!)/((12-8)!)


12 P 8 = (12!)/(4!)


12 P 8 = (12*11*10*9*8*7*6*5*4!)/(4!)


12 P 8 = 12*11*10*9*8*7*6*5


12 P 8 = 19958400



So there are <font color="red">19,958,400</font> different ways to do this (assuming order matters).
