WebQuestion 1: Let A and B are two independent events such that P (A) = 0.2 and P (B) = 0.8. Find P (A and B), P (A or B), P (B not A), and P (neither A nor B). Answer : Given P (A) = 0.2 and P (B) = 0.8 and events A and B are independent of each other. P (A and B) = P ( A ∩ B) = P (A) P (B) = 0.2 × 0.8 = 0.16.

WebNo, mutually exclusive events are events that cannot occur simultaneously: they are disjoint. If A and B are disjoint, then P ( A ∪ B) = P ( A) + P ( B) = 0.42 + 0.38 = 0.80. That’s not the case here, so A and B are not mutually exclusive. WebA and B are two events with P(B) = 0.38, P(A and B) = 0.23, P(B A) = 0.42 Find P(A) Round to two decimal places

Then, P (A) = 1 / 6 and P (B) = 1 / 6. In this case, A and B are mutually exclusive as we cannot get 2 and 3 in the same roll of a die. Hence, P (A∩B) = 0. Using the P (A∪B) formula, P (A∪B) = P (A) + P (B) - P (A∩B) P (A∪B) = 1 / 6 + 1 / 6 - 0 = 2 / 6 = 1 / 3 gxo logistics uk wellingboroughWebProblem states: Consider two events A and B, with P ( A) = 0.4 and P r ( B) = 0.7.
