यदि \(A=\{1,2,3,4,5\}\) और \(B=\{0,1\}\) हों, तो कितने फलन \(f:A\to B\) ऐसे हैं जिनमें कम से कम दो इनपुटों की छवि (1) हो?
If \(A=\{1,2,3,4,5\}\) and \(B=\{0,1\}\), how many functions \(f:A\to B\) have at least two inputs with image (1)?
Explanation opens after your attempt
B. (26)
Concept
There are \(2^5=32\) total functions. Excluding cases with (0) or (1) occurrence of (1), namely (1+5=6), leaves (26).
Why this answer is correct
The correct answer is B. (26). There are \(2^5=32\) total functions. Excluding cases with (0) or (1) occurrence of (1), namely (1+5=6), leaves (26).
Exam Tip
कुल \(2^5=32\) फलन हैं। (0) या (1) बार (1) आने वाले (1+5=6) फलन हटाने पर (26) बचते हैं।
