Question 368806
john has 3 pairs of pants, 4 shirts and 2 belts. how many combinations can he wear? can you tell me a formula for this, i can do it manually but would like a formula,
-----
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
