Question 984568: Hi! I am finite mathematics and we are studying "sets". Here is my question.
U= {1,2,3,4,5,6,7,8,9,10}
A={1,3,5,7,9}
B={2,4,6,8,10}
C={1,2,4,5,8,9}
QUESTION: (AuBuC)^C

I'm going to go way out on a limb here and guess that you are using the caret mark to mean intersection, so that your question is actually:

Presuming that is the case, note that the union of A and B is U, so the union of A and B and C is still U, and since C is a proper subset of U, the intersection of U and C is simply C.
