A company car that has a seating capacity of eight is to be used by eight employees who have formed a car pool. If only four of these employees can drive, how many possible seating arrangements are there for the group? So i understand that i should use the permuation formula becasue... ORDER MATTERS! but I'm not sure how the heck im supposed to set this up. guys please don't just post a link to somthing and make me read/ pick through a 4 page article to find what i need which may or may not be there.
