Suppose that A and B are events defined on a common sample space and that the following probabilities are known: P(A) = 0.3 P(B) = 0.4 and P (A/B) = 0.2 Find P (A or B).
Answer to relevant QuestionsSuppose that A and B are events defined on a common sample space and that the following probabilities are known P (A or B) = 0.7, P(b) = 0.5, and P (A,B) = 0.2 Find P(A) The probability of A is 0.5.The conditional probability that A occurs given that B occurs is 0.25.
