Use a Venn Diagram and the given information to determine the number of elements

Question

Use a Venn Diagram and the given information to determine the number of elements in the indicated set. n(U) = 235, n(A) = 80, n(B) = 100, n(A Intersection B) = 35, n(A Intersection C) = 38, n(A Intersection B Intersection C) = 18, n(A' Intersection B Intersection C') = 47, and n(A' Intersection B' Intersection C') = 60. Find n(C). (A) 86 (B) 30 (C) 46 (D) 50 Suppose P(C) = .048, P(M Intersection C) =.044, and P(M Union C) = .524 Find the indicated probability. P(M' Union C') (A) .466 (B) .956 (C) .004 (D) .524

Explanation / Answer

24)

P(C) = .048
P(M int C) = .044
P(M union C) = .524

P(M' union C') = 1-P(M int C) = 1-.044 = .956

Answer is B
