Question

You have a CD with 14 cuts on it, and another with 11 cuts by a different artist. You wish to make a compilation from all these songs containing just 3 different cuts which you will play for your friends. How many possible ways can you arrange 3 cuts copied from these two CDs? (Count two compilations as different if they have the same three songs in a different order.)

A. 25
B. 13,800
C. 2,300
D. 17,550
E. 180
