Answer:
12
Step-by-step explanation:
Let's calculate how many possible outfits does Tobias has.
Hats: 2, Shirts: 3, Pants: 2
If he's picking everything at random blindly from his closet, he could pick any of the hats, any of the shirts and any of the pants. That makes a total of:
2 x 3 x 2 = 12 possible combinations.
That doesn't mean the arrangement will look pretty :-)
