\(A=\{1,2,3,4\}\) पर \(R=\{(a,b):a+b\ge 5\}\) स्वसम क्यों नहीं है?
Why is \(R=\{(a,b):a+b\ge 5\}\) on \(A=\{1,2,3,4\}\) not reflexive?
Explanation opens after your attempt
A. क्योंकि \((1,1)\notin R\)Because \((1,1)\notin R\)
Concept
For ((1,1)), \(1+1\ge 5\) is false. One missing self-pair is enough to break reflexivity.
Why this answer is correct
The correct answer is A. क्योंकि \((1,1)\notin R\) / Because \((1,1)\notin R\). For ((1,1)), \(1+1\ge 5\) is false. One missing self-pair is enough to break reflexivity.
Exam Tip
((1,1)) के लिए \(1+1\ge 5\) असत्य है। स्वसमता टूटने के लिए एक आत्म युग्म का गायब होना काफी है।
