If equivalence classes of (R) on (A={1,2,3,4}) are ({1,4}), ({2}), and ({3}), how many pairs are in (R)?यदि (A={1,2,3,4}) पर (R) के समतुल्यता वर्ग ({1,4}), ({2}), ({3}) हैं, तो (R) में कितने युग्म होंगे?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 66
Step 1: The class ({1,4}) gives (2^2=4) pairs. Step 2: The singleton classes ({2}) and ({3}) give (1+1) pairs. Step 3: Total pairs are (4+1+1=6).चरण 1: वर्ग ({1,4}) से (2^2=4) युग्म मिलते हैं। चरण 2: ({2}) और ({3}) से (1+1) युग्म मिलते हैं। चरण 3: कुल युग्म (4+1+1=6) हैं।
