यदि \(A={x:x\in\mathbb{N},2\le x\le5}\) और \(B={y:y\in\mathbb{N},y<4}\) हैं, तो (n\(A\times B\)) कितना है?
If \(A={x:x\in\mathbb{N},2\le x\le5}\) and \(B={y:y\in\mathbb{N},y<4}\), what is (n\(A\times B\))?
Explanation opens after your attempt
Correct Answer
C. (12)
Concept
\(A=\{2,3,4,5\}\) and \(B=\{1,2,3\}\). Hence (n\(A\times B\)=4\times3=12).
Why this answer is correct
The correct answer is C. (12). \(A=\{2,3,4,5\}\) and \(B=\{1,2,3\}\). Hence (n\(A\times B\)=4\times3=12).
Exam Tip
\(A=\{2,3,4,5\}\) और \(B=\{1,2,3\}\) हैं। इसलिए (n\(A\times B\)=4\times3=12)।
