Let B = {1, 3, 5, 7, 9} and C = {11, 12, 13, 14, 15}. Write B ∩ C using the listing method. (Enter EMPTY or ∅ for the empty set.)

Answer 1

Hi Fabiola,

That upside down "U" means "intersection".

We are looking for the intersection of set B and set C.

Which means we are looking for the elements of set B that are also elements of set C.

In this case, there are no elements in set B that are also in set C. So the answer is

THE EMPTY SET
