Let A and B be events such that A c B. Also, let P(A) = 0.30, and P(B) = 0.45. Calculate the following probabilities. Hints: Venn Diagrams will be useful. Remember the axioms of probability (a) P(AUB) (b) P(Ac) (c) P(An B) (d) P(Acn B)
(1 point) Suppose that A and B are two events for which P(A)-0.15. P(B) A. P(A and B) B. P(A or B) 0.72, and P(BIA)-0.38 Find each of the following:
5. Independent events A and B are such that P(A) = 0.45 and P = 0.18. Find: a) P(B) b) P(A U B) c) P (A B) (A, λ B')
Suppose A and B are two events for which P(A) =0.18, P(B) = 0.45, and P(A or B) = 0.54. Find P( A and B) Find Are A and B mutually exclusive? (Support your answers!) Are A and B independent?
