Webindependent such that P(A∩B) = P(A)P(B), then A, Bc are also statistically independent such that P(A∩Bc) = P(A)P(Bc). Proof. Consider A = A∩(B ∪Bc) = (A∩B)∪(A∩Bc). The ﬁnal expression denotes the union of disjoint sets, so there is P(A) = P(A∩B)+P(A∩Bc). Since, by assumption, there is P(A∩B) = P(A)P(B), it follows that WebApr 5, 2024 · Any sets A and B, P(A ∪ B) = P(A) ∪ P(B) Ask Question Asked 5 years, 11 months ago. Modified 5 years, 11 months ago.
