यदि \(A=\{a,b,c,d\}\) और \(B=\{b,d,e\}\) हैं, तो (A-B) क्या होगा?
If \(A=\{a,b,c,d\}\) and \(B=\{b,d,e\}\), what will be (A-B)?
Explanation opens after your attempt
A. ( {a,c} )
Concept
(A-B) contains elements of (A) that are not in (B). In set difference, changing order can change the answer.
Why this answer is correct
The correct answer is A. ( {a,c} ). (A-B) contains elements of (A) that are not in (B). In set difference, changing order can change the answer.
