If n(A)=2 and n(B)=2 then how many possible relations are there from A to B?
यदि n(A)=2 और n(B)=2 है तो A से B तक possible relations कितने होंगे?
Show answer and explanation
Correct Answer
C. 16
ExplanationStep 1: A relation from A to B is a subset of A × B. Step 2: n(A × B)=2×2=4 so relations are 2^4 = 16. Step 3: Count subsets of Cartesian product for relation count.
Step 1: Relation A से B तक A × B का subset होता है। Step 2: n(A × B)=2×2=4 इसलिए relations 2^4 = 16 होंगे। Step 3: Relation count के लिए Cartesian product के subsets गिनें।
