यदि (A-B) का अर्थ \(A\setminus B\) है, तो कौन-सा कथन सामान्यतः गलत है?
If (A-B) means \(A\setminus B\), which statement is generally false?
Explanation opens after your attempt
Correct Answer
A. \(A\setminus B=B\setminus A\)
Concept
Set difference is not commutative, so \(A\setminus B\) and \(B\setminus A\) are generally different. Order matters greatly in difference.
Why this answer is correct
The correct answer is A. \(A\setminus B=B\setminus A\). Set difference is not commutative, so \(A\setminus B\) and \(B\setminus A\) are generally different. Order matters greatly in difference.
Exam Tip
समुच्चय अंतर अदला-बदली योग्य नहीं है, इसलिए \(A\setminus B\) और \(B\setminus A\) सामान्यतः अलग होते हैं। अंतर में क्रम बहुत महत्वपूर्ण है।
