My little sister was doing a practice maths paper (preparing for entrance exams into secondary schools) and she came across this question, which she got stuck on. As the one who marks her papers she asked me if I could help her: but the wording of this problem stumped me too. I don't have a mark scheme (though maybe one does exist), so I don't know what the correct answer is.
The problem goes as such:

What does the question mean by "less than even"? Does it mean less than 50%, or less than 1/3 (since there are three numbers on the wheel)?
