WebSimilarly, A∪B = A+B−A∩B is wrong; the equality should be between probabilities, not sets, i.e., P(A∪B) = P(A)+ P(B) − P(A ∩ B). Remember that arithmetic operations (+, −, etc.) between sets don’t make sense; when dealing with sets themselves (rather than their probabilities), you must use set-theoretic notation (∪, ∩ ...

WebSolution: By De Morgan’s law, P(A0 ∩ B0) = P((A ∪ B)0) = 1 − P(A ∪ B) = 1 − 0.7 = 0.3 and similarly P(A0 ∩ B) = 1 − P(A ∪ B0) = 1 − 0.9 = 0.1. Thus, P(A 0) = P(A0 ∩B )+P(A0 ∩B) = 0.3+0.1 = 0.4, so P(A) = 1−0.4 = 0.6 . 5. Given that A and B are independent with P(A) = 2P(B) and P(A∩B) = 0.15, find P(A0 ∩B0).

WebP(A0 ∩B) = P(B)−P(A∩B) = P(B)−P(A)P(B) Indep of A,B = (1−P(A))P(B) = P(A0)P(B) Therefore, A0 and B are independent. • A0 and B0 are independent. In this case, show that P(A0 ∩B0) = P(A0)P(B0) We might be able to do this straight off: P(A 0∩B ) = P((A∪B)0) M.E. sets = 1−P(A∪B) = 1−(P(A)+P(B)−P(A∩B) = 1−P(A)−P(B ...
