The Attempt at a Solution
So I tried drawing Venn diagrams and came to the conclusion that they must be true but when I asked my professor for help all he said was that Venn diagrams don't count as formal proofs and that I was wrong in any case. Now I am just totally confused. Any help will be appreciated
