    A survey of 118 college students was due to find out what electives courses they were taking. Let A= set of those taking art, B = set of those taking basketweaving, 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 intercept B intercept C) =2
    n(A intercept B) =12
    n( (A intercept C)=15
    n (B intercept C) =23

    How many students were not taking any of these electives?
