Thread: Set Theory

I got it!


Thanks!

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!
