A' means everything in U that is not in A so A' = {5,6,7,8,9,10} Similarly C' = {1,3,4,9,10} So BUC'={1,2,3,4,9,10} Now the question is "What do A' and B U C' have in common? The answer is {9,10}

Actually thats not a answer for the choice: It says Find the following set: A' ∩ (B ∪ C') A' ∩ (B ∪ C') = A) {1,5} , B) {6}, C) {1,2,3}, D) { }

I'll work through it again and see if I can find an error. The first set is the universal set, right?
