Question

please help me get started:

Answer 1

its 16.

Answer 2

Your union of B and C will give you a max of 24 elements. Any intersection with that will produce at most 16 elements because that is the total in set A.

Answer 3

how would it be 16? please explain

Answer 4

There are only 16 elements in A so even if all those 16 were in the union of B and C, the common elements have to be in both sets. And there are only 16 in A that could possibly also be in the union of B and C.
