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

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) = [tex]\frac{P(A\cap B)}{P(A)}[/tex]
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.
