If (R={(1,2),(2,1),(1,1),(2,2)}) on (A={1,2,3}), why is (R) not reflexive?यदि (A={1,2,3}) पर (R={(1,2),(2,1),(1,1),(2,2)}), तो (R) स्वपरक क्यों नहीं है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Because ((3,3)) is missingक्योंकि ((3,3)) अनुपस्थित है
Step 1: Reflexivity applies to every element of the whole set. Step 2: Since (3) is in the set, ((3,3)) must be present. Step 3: Having only some self-pairs does not complete reflexivity.चरण 1: स्वपरकता पूरे समुच्चय के हर तत्व पर लागू होती है। चरण 2: (3) समुच्चय में है, इसलिए ((3,3)) होना चाहिए। चरण 3: कुछ स्वयं युग्म होने से स्वपरकता पूरी नहीं होती।
