You can put this solution on YOUR website! Given the group(Allen,Brenda,Chad,Dorothy,Eric,Fred,Gail) determine ther number of ways of choosing a president, vice president, secretary and treasurer
--------------------
Order is implied by the offices listed, so the answer is a number of permutations. That answer is 7P4 = 6!/(6-4)! = 7*6*5*4*3 = 840
This is equivalent to 7 ways to choose the pres, 6 ways to choose the vp,
etc.
---------------
If the offices do not imply order the answer is 7C4 = 35
This is equivalent of 35 ways to simply picking 4 people from the 7 available.
