hmm, and if it's just like this? \[A \subset B\] ?

Ah wait I'm still a bit confused. So if I'm asked: If A = {2, 4, 6, 8, 10} and B = {4, 8, 10}, then which of the following statements is false? 1) A ∩ B = B 2) B⊆B 3) A⊂B Then it would be 3 because A is not a subset of B, it is B that is a subset of A.. right?

u need to prove the three staments

No, I don't. I need to choose which one out of these (A ∩ B = B, B⊆B, and A⊂B) are false.

(1) {2, 4, 6, 8, 10} ∩ {4, 8, 10}= {4, 8, 10} true because is a intersection {2, 4, 6, 8, 10} ∪ {4, 8, 10}= {4, 8, 10} false is support to be equal to {2, 4, 6, 8, 10}

It's not A ∩ B = B because it's an intersection, nor B⊆B because {4, 8, 10} is the same as {4, 8, 10}.. so the one that's false is what I said earlier: A⊂B...

I didn't have a book. I have online schooling where they rarely give me well written lessons. (If I could just read the book I wouldn't be using OpenStudy.)
