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
Correct Answer

A. ( {a,d} )

Step 1

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.

Step 2

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.

Step 3

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।
