A: The probability of a number appearing on the wheel for the first time is 36:1 in a single spin. The probability of a number appearing on the wheel for the last time is 35:1 in a single spin. Since 12 has appeared twice in the 14 spans, the probability of a number appearing on the wheel for the 15th span is 12:1 in a single spin. The man has a 35:12 chance of winning if he bets on either 16 or 12. The answer is (B).
Answer the following multiple choice question with options (a), (b), (c), (d), (e) by reasoning step-by-step.
