Suppose a simple random sample of voters are surveyed from each state. What is the probability that the survey will show a greater percentage of Republican voters in the second state than in the first state? The correct answer is C. Therefore, the probability that the survey will show a greater percentage of Republican voters in the second state than in the first state is 0.
The probability of selecting a blue ball in the first draw is 0! What is the probability of rolling a 5 when a die is rolled. Let X be the number of students answering yes when 8 students are selected at random and asked the same question.

The motivation for this clearly written collection lies in the belief that challenging problems help to develop, and to sharpen, our probabilistic intuition much better than plain-style deductions from abstract concepts. The selected problems fall into two broad categories. Problems related to probability theory come first, followed by problems related to the application of probability to the field of mathematical statistics. All problems seek to convey a non-standard aspect or an approach which is not immediately obvious. The word puzzles in the title refers to questions in which some qualitative, non-technical insight is most important. Ideally, puzzles can teach a productive new way of framing or representing a given situation.
