Each voter makes a choice from three candidates, 1, 2, and 3. We consider the votes of just two voters, Al and Bill, so the sample space S consists of all pairs, where the members of the pair are chosen from 1, 2, and 3.
a. List all elements of S.
b. List all outcomes in the event A that Al and Bill make the same choice.
c. List all outcomes in the event B that neither of them vote for candidate 2.
