Need help with Probability Question

[tariq20]

Tony and Antoine went trick or treating on Halloween. They always visit their algebra teacher's house last because she has the best candy. This year she had:
5 Snickers
7 Reese's
3 packs of M&M's

Tony hates M&M's and Reese's.

Here is the question:
If he chooses 1 piece of candy without looking, which choice below represents the probability that chooses candy that he does not hate?
A. 33.3%
B. 46.6%
C. 53.3%
D. 87.5%

Please help me understand this.
