3. For two events A and B, given that P(A) = 0.4, P(B) = 0.5, and P(A | B) = 0.8, find the following: a. P(A ∩ B) b. P(A | B) c. P(B | A) Are the events A and B independent? Explain:
Pritesh R.
For two events A and B, P(A) = 0.6 and P(B) = 0.3. (a) If A and B are independent, then P(A|B) = P(A ∩ B) = P(A ∪ B) = (b) If A and B are dependent and P(A|B) = 0.3, then P(B|A) = P(A ∩ B) =
