Question

[URGENT] Suppose A and B are dependent events. If P(A) = 0.4 and P(B A) = 0.8, what isP(A B)?​

Answer 1

Answer:

Option (B)

Step-by-step 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) = $\frac{P(A\cap B)}{P(A)}$

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.
