3. Study these examples. Let U be the universal set. U = {1, 3, 5, 6, 7, 8, 9} A = {1, 3, 6, 8} B = {5, 6, 7} A’ = {5, 7, 9} 2. B’ = {1, 3, 8, 9} (A B)’ = { 6 }’ = { 1, 3, 5, 7, 8, 9 } (A U B)’ = {1, 3, 5, 6, 7, 8}’ = { 9 } A ’ B = = {5, 7, 9} {5, 6, 7} = {5, 7} Study these examples. Let U be the universal set. U = {1, 3, 5, 6, 7, 8, 9} A = {1, 3, 6, 8} B = {5, 6, 7} A’ = {5, 7, 9} 2. B’ = {1, 3, 8, 9}

4. A’ = {8, 10, 13, 17} B’ = {2, 19, 5}
