Use a Venn diagram to answer the question.A survey of 138 college students was done to find out what elective courses they were taking. Let A = the set of those taking art; B = the set of those taking basket weaving; and C = the set of those taking canoeing. The study revealed the following information:n(A) = 45; n(B) = 55; n(C) = 40; n(A ? B) = 12; n(A ? C) = 15; n(B ? C) = 23; n(A ? B ? C) = 2.How many students were not taking any of these electives?
