A universal set contains only sets A and B. If A∩B = Ø and A and B are not the empty set, then all of the following are true except A and B are disjoint. A is equal to B complement. A∪B={} A is not a subset of B.

    Think about it :) In English, A∩B = Ø Just means A and B have no elements in common :)

    Or, if you want a quicker way, neither A nor B is an empty set, so how can it be that A∪B={} or that there are no elements in A or in B?
