P what F? Intersection? Union? I don't know xP

anonymous · Answer

this is exactly why im asking, supper confusing

anonymous · Answer

the answer would be D

anonymous · Answer

Well, if it was union. It would be D because it is the set of all elements of both. You can exclude C period because there are no duplicates in sets. If it is intersection it is A. Because it has only the elements that are present in both. The rest don't make any sense.
