The correct formula to interpret the answer to an "or" probability scenario, which involves two events A and B, is:
\[ P(A \cup B) = P(A) + P(B) - P(A \cap B) \]
This means that to find the probability of either event A or event B occurring, you add the probability of A and the probability of B, and then subtract the probability of both A and B occurring (since they are counted twice).
So the correct response is: P(A) + P(B) - P(A and B).
