Let A and B be sets. The union of A and B is A U B = {x|x € A V x € B}. The intersection of A and
B is An B = {x E A A x € B}. The complement of a set A is A = {x]x € A}. Show that
(A U B) = AN B. Prove your result by using the definitions of union, intersection and complement of a
set. Prove that (A U B) CANB that AN BC (A U B). Justify your steps. Do not use Venn Diagrams in
your proof.
