Voting Paradox

Stage: 4 and 5 Challenge Level: Challenge Level:2 Challenge Level:2

How many different possible ways can each of the three voters vote?
For a paradox we are looking for situations in which

(A beats B beats C beats A) or (B beats A beats C beats B) etc.

Try counting the number of ways in which such situations are possible. To reduce the number of cases to analyse, you might consider what happens if two voters agree on their first choice.
