Answer to relevant QuestionsA and B are events defined on a sample space, with P(A) = 0.7 and P(B0A) = 0.4. Find P(A and B) Juan lives in a large city and commutes to work daily by subway or by taxi. He takes the subway 80% of the time because it costs less, and he takes a taxi the other 20% of the time. When taking the subway, he arrives at work ...Suppose 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 table here shows the average number of births per day in the United States as reported by the CDC (Centers for Disease Control).
