यदि \(A\cap B=\varnothing\), (n(A)=p) और (n(B)=q), तो (n\(A\cup B\)) क्या है?
If \(A\cap B=\varnothing\), (n(A)=p) and (n(B)=q), what is (n\(A\cup B\))?
Explanation opens after your attempt
Correct Answer
A. (p+q)
Concept
Disjoint sets have no common elements, so the union size is (p+q). If the intersection is empty, no subtraction is needed.
Why this answer is correct
The correct answer is A. (p+q). Disjoint sets have no common elements, so the union size is (p+q). If the intersection is empty, no subtraction is needed.
Exam Tip
असंबद्ध समुच्चयों में कोई साझा तत्व नहीं होता, इसलिए संघ की संख्या (p+q) है। प्रतिच्छेद रिक्त हो तो घटाने की जरूरत नहीं।
