If A = {1 2 3} then how many ordered pairs are in the identity relation?
यदि A = {1 2 3} है तो identity relation में ordered pairs कितने होंगे?
Show answer and explanation
Correct Answer
C. 3
ExplanationStep 1: Identity relation has pairs like (a a). Step 2: A has 3 elements so there are 3 identity pairs. Step 3: The number of identity pairs equals the number of elements in the set.
Step 1: Identity relation में (a a) जैसे pairs होते हैं। Step 2: A में 3 elements हैं इसलिए 3 identity pairs होंगे। Step 3: Identity relation की pair count set के elements जितनी होती है।
