Question 127112
Your set-up and answer are correct.


Think of it this way:


First he has to decide on a pair of pants and he has 8 different choices.  For each of those choices he has a choice of 5 different shirts, so that gives him 8 times 5 = 40 different pant/shirt combinations.  (I hope none of the pants are striped and none of the shirts have polka-dots).  For each those 40 possibilities, he has 3 different ties he could select, so altogether he has 40 times 3 = 120 different outfits, and some of them may be acceptable to wear in public.
