8. Critical Thinking For a class activity, your group has been assigned the task of generating a quiz question that requires use of the formula for conditional probability to compute P1B | A2. Your group comes up with the following question: “If P1A and B2 5 0.40 and P1A2 5 0.20, what is the value of P1B | A2?” What is wrong with this question? Hint: Consider the answer you get when using the correct formula, P1B | A2 5 P1A and B2/P1A2.
