Auniversal set U consists of 18 elements. If sets A, B, and C are proper subsets of U and n(U) = 18, n(An B) = n(An C) = n(BnC) =9, n(A NBNC) =6, and n(A UBUC) = 15, determine each of the following. a) n(A U B) b) n (A' UC) c) n(ANB) a) n(A U B) = 15 (Simplify your answer.) b) n (A' UC) =O (Simplify your answer.)
