Among 150 persons interviewed as part of an urban mass transportation study, some live more than 3 miles from the center of the city \((A)\), some now regularly drive their own car to work \((B)\), and some would gladly switch to public mass transportation if it were available (C). Use the information given in Figure 3.11 to find

(a) \(N(A)\);

(b) \(N(B)\);

(c) \(N(C)\);

(d) \(N(A \cap B)\);

(e) \(N(A \cap C)\);

(f) \(N(A \cap B \cap C)\);
(g) \(N(A \cup B)\);
(h) \(N(B \cup C)\);
(i) \(N(\bar{A} \cup \bar{B} \cup C)\);
(j) \(N[B \cap(A \cup C)]\).
