What is n(U)?Class 10SetsVenn DiagramsLevel 14Easy MathematicsAssertion: If A ∩ B = ∅, then n(A ∪ B) = n(A) + n(B). Reason: Disjoint sets have no common elements or common region. Choose the correct option.Class 10SetsVenn DiagramsLevel 14Medium MathematicsAssertion: n(A ∪ B) = n(A) + n(B) − n(A ∩ B). Reason: Elements of A ∩ B are counted twice in n(A) + n(B).
