Marcie is trying to decide which photographs to put into a photo frame that holds only six photographs. If Marcie has a total of 15 photographs from which to choose, how many different ways can six photographs be arranged in the frame?

For 1st photograph options available = 15.
for 2nd = 14
for 3rd = 13 .. and so on
So total number of ways = 15 * 14 * 13 * 12 * 11 * 10 = 3603600
