A survey was conducted among 74 patients admitted to a hospital cardiac unit during a two-week period. The data of the survey are shown below. Let B = the set of patients with high blood pressure. Let C = the set of patients with high cholesterol levels. Let S = the set of patients who smoke cigarettes. n(B) = 30 n(C) = 34 n(S) = 34 n(BNS) = 13 n(BNC) = 11 n(B n cns) = 9 n[(BNC) U (BNS) U (CNS)] = 20
