WebThe tutor @robertb has a great solution. I don't have much, if anything, to add really except for the fact that if A and B were independent, then, P(A B) = P(A) P(B A) = P(B) Both must be true for A and B to be independent. We're told that P(B) = 0.30 and P(B A) = 0.48 which contradicts the second equation shown above.

Given that P(A) = 0.2, P(B) = 0.7, and P(A B) = 0.15, find P(A0 ∩B0). Solution: By De Morgan’s Law, P(A0 ∩ B0) = P((A ∪ B)0) = 1 − P(A ∪ B) = 1−P(A)−P(B)+P(A∩B). Using the given values of P(A) and P(B) and P(A∩B) = P(A B)P(B) = 0.15 · 0.7 = 0.105 (the multiplication formula), we get P(A0 ∩ B0) = 1−0.2−0.7+0.105 ... motorcycle shop in readingWeb18 apr. 2024 · 2 Answers Sorted by: 1 Yes.
