यदि (A\triangle B=\(A\setminus B\)\cup\(B\setminus A\)) है और \(A=\{1,2,4,6\}\), \(B=\{2,3,4,5\}\), तो \(A\triangle B\) क्या है?
If (A\triangle B=\(A\setminus B\)\cup\(B\setminus A\)) and \(A=\{1,2,4,6\}\), \(B=\{2,3,4,5\}\), what is \(A\triangle B\)?
Explanation opens after your attempt
Correct Answer
A. ({1,3,5,6})
Concept
The symmetric difference contains elements present in exactly one set, so it is ({1,3,5,6}). Do not include common elements.
Why this answer is correct
The correct answer is A. ({1,3,5,6}). The symmetric difference contains elements present in exactly one set, so it is ({1,3,5,6}). Do not include common elements.
Exam Tip
सममित अंतर में वे तत्व आते हैं जो केवल एक समुच्चय में हों, इसलिए ({1,3,5,6}) है। साझा तत्वों को हटाना न भूलें।
