Answer:
A. Event A is not dependent on Event B.
Explanation:
You have two events A and B such that P(A| B) = 0.4 and P(A) = 0.4.
This means that the probability of event A happening, given that B happened is 0.4, which is also the same probability of event A happening.
Since these probabilities are equal, event A is independent from option B, and the correct answer is given by option A.
