4. Let's say that for one of the two questions you can narrow the answer choices down to three. Now your chance of getting that question right by guessing is. What is the new expected value for the number of questions you'd get right by guessing? What are the new variance and standard deviation of this random variable? Drawing another tree diagram and making another probability distribution table may help you answer this question.
