Answer 6

The first one is correct, the second is also correct, and the third one isn't correct.

The answer you selected for \(C^{\prime}\) is actually the set \(C\) itself. In the problem there, they told you \(C\) was the set of positive odd numbers. Hence, the complement of \(C\) (i.e. \(C^{\prime}\)) should be the set of positive numbers that isn't odd. So that now begs the following question: if the number isn't odd, then it has to be what?

Do you think you can take things from here? :-)

Answer 7

@ChristopherToni It would be A, then?
