Question
P(A) = 0.40P(B) = 0.50P(A and B) = 0.10What is P(B|A)?A.0.50B.0.25C.0.10D.0.20
Solution
The formula for conditional probability is P(B|A) = P(A and B) / P(A).
Given that P(A) = 0.40, P(B) = 0.50, and P(A and B) = 0.10, we can substitute these values into the formula:
P(B|A) = 0.10 / 0.40 = 0.25
So, the answer is B. 0.25.
