b. In how many ways can a committee of 5 be formed if each student has a different responsiblity?
Answer by josmiceli(19441)   (Show Source):
You can put this solution on YOUR website! When they say that each student has a different
responsibility, it means there are 5 different jobs
on the committee, and the order of the same 5
people selected matters, as in:
1, 2, 3, 4, 5 is different from
2, 1, 3, 4, 5
so, permutations, not combinations are used
---------------------------------------------
P( 15, 5 ) = 
P( 15, 5 ) = 
P( 15, 5 ) = 
P( 15, 5 ) = 
There are 360,360 ways to form a committee
