In this case, n(C) = 44 and n(C ∩ J) = 10 + 27 = 37, so the people who like classical but not jazz will be given by n(c) - n(C ∩ J) = 44 – 37 = 7 6.13 Cartesian Products Suppose we are given two sets, A and B, then their Cartesian products would be given by: A × B = {(a, b)|a ∈ A and b ∈ B} Further, n (A X B ) = n(A) X n(B) For instance, given that A = {1, 2} and B = {5, 6} Then, {1, 2} X {5, 6}= {(1, 5), (1, 6), (2, 5), (2, 6)}
