The first two images are the question
The last one is the explanation from the prof which I do not understand.
I don't understand why the answer shouldnt be D (it's E)
To me, the set means "All elements that fall outside of A, plus all elements falling outside of R/V/R&V." Which would make the answer to the problem choice D Can someone translate into english what the set means, and possibly explain in another way why the answer is E?
