WebGiven P(A) = 0.4, P(B) = 0.5 and P(A⋃B)=0.9,then: (a) A and B are not mutually exclusive events (b) A and B are equally likely events (c) A and Bare independent events (d) A and B are mutually exclusive events MCQ 6.57 If P(B/A) = 0.50 and P(A⋂B) = 0.40, then p(A) will be equal to: (a) 0.40 (b) 0.50 (c) 0.80 (d) 1 MCQ 6.58 WebThe probability of the entire outcome space is 100%. (P(S) = 100%. because the outcome space contains every possible outcome.) If two events are disjoint, the probability that either of the events happens is the sum of the probabilities that each happens. (If AB = {}, P(A ∪ B) = P(A) + P(B).)
