Error in the first picture it should be (B & D), and NOT (B & C)

Showing set equations that are not identities. About A set equation is not an identity if there are examples for the variables denoting the sets that cause the equation to be false. For example A U B = A B is not an identity because if A = {1, 2} and B-(1), then A u B = {1, 2} and A n B = {1}, which means that A u B . Show that each set equation given below is not a set identity. B & C A (BnA) A (B -A) U A A
