**MathMate**, Thursday, October 27, 2011 at 9:15pmTake out Ed and Gail (7 people left). Choose 5 at a time to take pictures without the couple. There are

N1=7!/(7-2)! possible pictures.

Now treat the couple as a single person, and get 3 other people for pictures (N2).

Don't forget to ask Gail and Ed to change places (2*N2)

Add up the two to get the total=N1+2N2
