यदि \(A=\{p,q\}\) और \(B=\{0,1\}\) है तो (A) से (B) में कुल कितने फलन बन सकते हैं?
If \(A=\{p,q\}\) and \(B=\{0,1\}\), how many functions can be formed from (A) to (B)?
Explanation opens after your attempt
Correct Answer
A. (4)
Concept
Each element (p) and (q) has (2) choices, so total functions are \(2^2=4\). Use \(|B|^{|A|}\) for counting.
Why this answer is correct
The correct answer is A. (4). Each element (p) and (q) has (2) choices, so total functions are \(2^2=4\). Use \(|B|^{|A|}\) for counting.
Exam Tip
हर तत्व (p) और (q) के लिए (2) विकल्प हैं इसलिए कुल \(2^2=4\) फलन हैं। गिनती में \(|B|^{|A|}\) प्रयोग करें।
