The simple answer is 120.
Explanation:
5p5 is the number of ways of picking 5 objects out of a group of 5 objects, where order matters.
Whenever you select ALL of the objects and order matters, the formula for nPn is n !
Since 5! 5(4) (3) (2) (1) = 120 , that answers the question at hand.
In general, though, if you are only selecting r of the objects -- not necessarily all of them:
nPr = n! / (n-r)!
