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

P(B | A ) = P(A and B)/P(A) = 0.40/0.20 = 2 Which is wrong here, Probability always lies in the interval 0 to 1.
