Answer:
Johan can make 8000 different outfits.
Step-by-step explanation:
Johan needs to pick one of each (shirt, pants, socks and shoes) to make a outfit. The number of socks he has is 20 pairs, so he has 20 possibilities for socks. In the same way, the number of possibilities for shoes is 5, for pants is 10 and for shirts is 8.
So, to find the number of outfits he can make, we need to multiply all the possibilities for each case, so:
Number of different outfits = 20 * 5 * 10 * 8 = 8000.
