Best ResponseYou've already chosen the best response.0Ah 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?

Best ResponseYou've already chosen the best response.0No, I don't. I need to choose which one out of these (A ∩ B = B, B⊆B, and A⊂B) are false.

Best ResponseYou've already chosen the best response.1(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}

Best ResponseYou've already chosen the best response.0It'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...
