On (A={1,2,3}), how many symmetric relations contain ((1,2)) but do not contain ((1,1))?(A={1,2,3}) पर कितने सममित संबंध ऐसे हैं जिनमें ((1,2)) हो लेकिन ((1,1)) न हो?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (2^4)(2^4)
Step 1: There are (6) independent groups in total. Step 2: The group containing ((1,2)) is fixed as included, and the diagonal pair ((1,1)) is fixed as excluded. Step 3: So (4) groups remain free, giving (2^4).चरण 1: कुल स्वतंत्र समूह (6) हैं। चरण 2: ((1,2)) वाला समूह लेना तय है और ((1,1)) वाला विकर्ण समूह न लेना तय है। चरण 3: दो समूह तय होने के बाद (4) समूह स्वतंत्र बचे, इसलिए संख्या (2^4) है।
