If (A={2,4,6}) and (R={(2,2),(4,4)}), why is (R) not reflexive?यदि (A={2,4,6}) और (R={(2,2),(4,4)}) है, तो (R) स्वतुल्य क्यों नहीं है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Because ((6,6)) is missingक्योंकि ((6,6)) नहीं है
Step 1: A reflexive relation must contain the self-pair of every element of (A). Step 2: For (6), the pair ((6,6)) is missing. Step 3: If even one required pair is absent, the relation is not reflexive.चरण 1: स्वतुल्य सम्बन्ध के लिए (A) के हर सदस्य का अपने-आप से युग्म होना चाहिए। चरण 2: (6) के लिए ((6,6)) नहीं दिया है। चरण 3: एक भी आवश्यक युग्म छूट जाए तो सम्बन्ध स्वतुल्य नहीं रहता।
