    u is the universal set. It is everything, m, n, and in this case outside of m and n.

    No need to be confused. You just asked about the universal set. You could ignore since it is not a part of the question. Have confidence. You already chose an answer, stand by it, and go to the next one.

    I blew that one, AUB means it is in A or B, so it should be 3, 4, 6, 7, 9
