यदि \(U=\{a,b,c,d,e\}\), \(A=\{a,b,d\}\) और \(B=\{b,c\}\) है, तो (A-B) क्या है?
If \(U=\{a,b,c,d,e\}\), \(A=\{a,b,d\}\), and \(B=\{b,c\}\), what is (A-B)?
Explanation opens after your attempt
A. ( {a,d} )
Concept
The common element (b) is removed from (A), leaving ({a,d}). Even when a universal set is given, find the difference only between the asked sets.
Why this answer is correct
The correct answer is A. ( {a,d} ). The common element (b) is removed from (A), leaving ({a,d}). Even when a universal set is given, find the difference only between the asked sets.
Exam Tip
(A) से (B) का समान अवयव (b) हटता है और ({a,d}) बचता है। सार्वत्रिक समुच्चय दिए होने पर भी अंतर केवल दिए गए दो समुच्चयों से निकालें।
