यदि \(A\triangle B=(A-B)\cup(B-A)\) है और \(A=\{a,b,c,d\}\), \(B=\{b,d,e,f\}\) हैं, तो \(A\triangle B\) क्या है?
If \(A\triangle B=(A-B)\cup(B-A)\) and \(A=\{a,b,c,d\}\), \(B=\{b,d,e,f\}\), what is \(A\triangle B\)?
Explanation opens after your attempt
A. ({a,c,e,f})
Concept
Common elements (b,d) are removed. Only elements that belong to exactly one set are taken.
Why this answer is correct
The correct answer is A. ({a,c,e,f}). Common elements (b,d) are removed. Only elements that belong to exactly one set are taken.
