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
Correct Answer

A. ({a,c,e,f})

Step 1

Concept

Common elements (b,d) are removed. Only elements that belong to exactly one set are taken.

Step 2

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.

Step 3

Exam Tip

समान तत्व (b,d) हट जाते हैं। केवल वे तत्व लिए जाते हैं जो ठीक एक समुच्चय में हों।
