SUMMARY
In the discussion, Brendan inquires whether events A and B are independent given that P(A) = 0.4 and P(A|B) = 0.4. The conclusion is definitive: events A and B are independent if P(A|B) equals P(A). This is validated by the independence condition P(A ∩ B) = P(A)P(B), which confirms that the probabilities align under the independence criterion.
