**MathMate**, Monday, August 22, 2011 at 4:22pmThe 7 letters of the word "COMBINE" are distinct, so there are 7 choices for the first letter, only 6 for the second, 5 for the third, and 4 for the fourth.

Since the choices are independent, by the rule of multplication, the number of choices is:

7*6*5*4

=?
