Answer 2

@Darlene11: if you want to know how to get the right answer for this problem, and for that other on of the same kind, it helps (very much) to first know what kind of numbers go in eaxh of thease sets.
So you do not just need to know that Z stands for integers, you also have to learn that integers are the set of numbers equal to {...-3,-2,-1,0,1,2,3,4,...}.

Each of the sets has its own definition. If you know the definitions, you can answer the question.
