On (A={1,2,3}), (R={(a,b):a+b>2}). (R) is not reflexive because which pair is missing?(A={1,2,3}) पर (R={(a,b):a+b>2}) है। (R) परावर्ती नहीं है क्योंकि कौन सा युग्म छूटता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((1,1))((1,1))
Step 1: Test the rule on ((1,1)). Step 2: (1+1=2), and (2>2) is false. Step 3: Missing one required self-pair makes the relation not reflexive.चरण 1: ((1,1)) पर नियम जांचें। चरण 2: (1+1=2), और (2>2) असत्य है। चरण 3: एक जरूरी अपने-अपने युग्म छूटने से संबंध परावर्ती नहीं रहता।
