यदि \(A=\{a,c,e,g\}\) और \(B=\{b,c,d,g\}\) है, तो (B-A) क्या है?
If \(A=\{a,c,e,g\}\) and \(B=\{b,c,d,g\}\), what is (B-A)?
Explanation opens after your attempt
C. ( {b,d} )
Concept
(B-A) leaves (b) and (d) because they are not in (A). Do not assume (A-B) and (B-A) are the same.
Why this answer is correct
The correct answer is C. ( {b,d} ). (B-A) leaves (b) and (d) because they are not in (A). Do not assume (A-B) and (B-A) are the same.
Exam Tip
(B-A) में (B) के (b) और (d) बचते हैं क्योंकि ये (A) में नहीं हैं। (A-B) और (B-A) को समान न मानें।
