Question

If W = {1, 2, 3, 4 …} and subset Z = {positive odd integers}, what is Z'?

{1, 2, 3, 4 …}

{ }

{5, 6, 7, 8 …}

{2, 4, 6, 8, …}

Answer 1

This is more of a math question - just letting you know for next time! And maybe this was on accident. And Z is none of those....

Answer 2

Well, actually, {}

Answer 3

But then, while Z is a subset of W, Z doesn't contain any odd numbers.

Answer 4

{} is "empty set" and is a subset of all sets, I think.
