Important Formulas from Sets Class 11 Chapter
Here are the key formulas from Class 11 Maths Solutions Chapter 1 Sets you must know. Trust me, these are your golden ticket to scoring full marks!
| Concept | Formula |
|---|---|
| Union of Two Sets | n(A∪B)=n(A)+n(B)−n(A∩B)n(A \cup B) = n(A) + n(B) – n(A \cap B) |
| Complement | A′=U−AA’ = U – A |
| Disjoint Sets | A∩B=∅A \cap B = \emptyset |
| De Morgan’s Laws | (A∪B)′=A′∩B′(A \cup B)’ = A’ \cap B’ |
| (A∩B)′=A′∪B′(A \cap B)’ = A’ \cup B’ |
