Events A and B cannot be disjoint because the sum of their probabilities exceeds 1, indicating there must be some overlap (i.e., a non-zero probability that both events occur). Disjoint events (mutually exclusive) have no outcomes in common, and thus, if both events were disjoint, the sum of their probabilities would not exceed 1.
