## Proof of n(A U B) = n(A) + n(B) – n (A ∩ B) by Venn Diagram

- Proof : Distribution Law of Union over Intersection
- Proof : Distribution Law of Intersection over Union
- De Morgan’s Laws
- Prove That A U (A ∩ B) = A
- Prove That : A ∩ (A U B) = A & (A – B) ∩ (B – A) = Φ
- n(A U B) = n(A) + n(B) – n (A ∩ B)
