They all look to be right except: 2nd F: A∩B⊂B IS true... and 2nd G: A∪B⊂A ISN'T necessarily true. Let A= {1,2,3}, B= {4,5}. A∪B = {1,2,3,4,5}, is not a subset of {1,2,3}.
Sorry, that's what I meant... I accidently put G and F on the same line. I meant to star F and not G... But somehow my answers were wrong? o__O
Really? Which ones?
Nvm! Thanks! I realized that C was actually right!
