You can put this solution on YOUR website! Well, the simple way to explain it is simply to multiply 3 by 4 by 2 and get 24 combinations...let me explain that logically to you...
For every one of four shirts, he can wear one of two belts...so that is eight different combinations.
For every pair of pants, he can wear any of the eight combos of shirt and belt. Since he has 3 pair of pants, 3 times 8 gives the same 24 combinations.

Counting Principle:
If step one of a process can be done in n1 ways
and step k can be done in nk ways,
the process can be done in n1*n2*n3*...*nk ways
-------------------------------------
Your problem
# of combinations is 3*4*2 = 24 ways
