(R={(1,2),(2,1),(2,3)}) is not symmetric because which pair is missing?(R={(1,2),(2,1),(2,3)}) सममित नहीं है क्योंकि कौन सा युग्म नहीं है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((3,2))((3,2))
Step 1: For ((2,3)), symmetry requires ((3,2)). Step 2: The pair ((3,2)) is not present in the relation. Step 3: If even one reverse pair is missing, the relation is not symmetric.चरण 1: ((2,3)) के साथ सममितता के लिए ((3,2)) चाहिए। चरण 2: दिए गए संबंध में ((3,2)) नहीं है। चरण 3: एक भी उलटा युग्म छूटने पर संबंध सममित नहीं रहता।
