Show your work

Back in a college statistics class, I got the following problem on an exam:

You are playing a card game, and there are 5 cards in a suit remaining to be divided between the person on your left and the person on your right. What are the odds that the person on your right has 3?

I showed no work and wrote down the (correct) answer. I got no credit. Maybe I was supposed to ask for the auction.
