Answer»

1. A – B = {4, 6, 8, 12}

2. B – C = {2, 7}

3. A – C = {2, 4, 6, 7, 8}

4. B – A = {9, 10}

5. C – A = {5, 9, 10}

6. (A ∪ B) – C = {2, 4, 6, 7, 8, 9, 10, 12} – {5, 9, 10, 12} = {2, 4, 6, 7, 8}.

7. A – (B ∩ C) = {2, 4, 6, 7, 8, 12} – {9, 10} = {2, 4, 6, 7, 8, 12}

8. (A ∩ B) – (C ∩ A) = {2, 7} – {12} = {2, 7}
