Best Answer

The empty set is the one that contains nothing at all.

The universal set contains everything.

Those are oversimplified definitions, but provide a good place to start.

When we talk about things in sets, we call the things contained in the sets elements. So we can be more precise and say the empty set is a unique set with no elements.

The universal set contains all elements INCLUDING itself.

It is the set of all elements we are considering or dealing with in a given problem. We use a capital U or sometimes capital E to mean the universal set. Now take ANY two sets, A and B.
