Let U = {0, 1, 2, 3, 4, 5,...},
A = {1, 2, 3, 4,...},
B = {4, 8, 12, 16,...}, and
C = {2, 4, 6, 8,...}. Determine the following:
A′ ∩ C

A' is the set of all elements of U which are not in A
= {0}
so A' ∩ C = {0} ∩ {2,4,6,8,..} = Ø or {} or null set 
Thank you Reiny. I actually got the same answer you did. Guess I understand it better than I thought. I just wanted to be sure I was doing it right. Thanks again :)
