3. Set Identities. Let A, B and C be sets. (a) It is tempting to say that (A – B) U (A – C) = A – (BUC). Provide a counterexample to show that the statement is false. Note: the sizes of A, B and C need not be big – e.g., at most 3. (b) Now prove using set identities that the following is true. Make sure that you write the set identity that you used at each step. (A – B) U (A – C) = A – (BNC). Make use of the fact that A – B = AN B.

Set Identities. Let A, B and C be sets.
(a)
It is tempting to say that
(А — В) U (A— C) %3 А — (BUC).
Provide a counterexample to show that the statement is false. Note: the sizes of A, B and C need
not be big – e.g., at most 3.
(b) Now prove using set identities that the following is true. Make sure that you write the
set identity that you used at each step.
(А — В) U (A— C) %3 А — (BnС).
Make use of the fact that A – B = AnB.
