Question

And belongs to intersection or not

Answer 1

I'm not sure I understand the question? Do you mean is "and" associated with the "intersection" of objects", similar to how "or" is associated with "union"?

Answer 2

Yes

Answer 3

Then, yes, if you want to consider AND, then you would take the intersection. If you want to consider OR, then you take the union. :)

Answer 4
