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?
