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 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?
This shows how to use a Venn diagram to determine how many elements are in each set.
