3. The expressions A (BUC) = (AB) n(AC). A (BAC) = (A B) U (AC) are known as De Morgan's Laws. They express a very useful relation between sets. Justify both of these laws with clearly labeled Venn diagrams. (You should have a Venn diagram for the lhs, and the r.h.s. of each expression) 4. Let G = (V, E) be an undirected graph, where V = {1, 2, 3, 4, 5, 6}, E = {e Pow(V) : le = 2} \ {{1,6}}. Draw G, and clearly label each vertex
