Answer:

Option (B)

Explanation:

If the probabilities of two events A and B are P(A) and P(B) then the conditional probability of an event that can be derived by the formula,

P(B | A) =
(P(A\cap B))/(P(A))

P(A ∩ B) = P(B|A) × P(A)

P(A ∩ B) = (0.8) × (0.4)

= 0.32

Therefore, Option (B) will be the correct option.
