Answer 1

Pretend that you're choosing an outfit today. 
First, you have 12 shirts to choose from, or 12 possibilities.
Second, you have 8 pairs of pants to choose from, or 8 possibilities.
FInally, you have 14 pairs of shoes to choose from, or 14 possibilities.

Multiply all these together and you get 12*8*14=1344 combinations of shirts, pants, and shoes.

Hope this helps!
