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 P(B A). Your group comes up with the following question: If P(A and B) 0.40 and P(A) 0.20, what is the value of P(B A)? What is wrong with this question? Hint: Consider the answer you get when using the correct formula, P(B | A) P(A and B) / P(A).
