WebbProve that P(A' ∩ B' )=1+ P(A ∩ B) − P(A) − P(B) This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. WebbP (A∩B) is the probability of both independent events “A” and "B" happening together, P (A∩B) formula can be written as P (A∩B) = P (A) × P (B), where, P (A∩B) = Probability of both independent events “A” and "B" happening together. P (A) = Probability of an event “A” P (B) = Probability of an event “B”
