यदि \(A\cap B=\varnothing\), (n(A)=24), और (n(B)=37), तो (n\(A\cup B\)) क्या है?
If \(A\cap B=\varnothing\), (n(A)=24), and (n(B)=37), what is (n\(A\cup B\))?
Explanation opens after your attempt
D. (61)
Concept
For disjoint sets, the common part is (0). Therefore, (n\(A\cup B\)=24+37=61).
Why this answer is correct
The correct answer is D. (61). For disjoint sets, the common part is (0). Therefore, (n\(A\cup B\)=24+37=61).
Exam Tip
असंबद्ध समुच्चयों में साझा भाग (0) होता है। इसलिए (n\(A\cup B\)=24+37=61)।
