यदि \(A=\{0,2,4\}\) और \(B=\varnothing\) हैं, तो (n\(A\times B\)) कितना है?
If \(A=\{0,2,4\}\) and \(B=\varnothing\), what is (n\(A\times B\))?
Explanation opens after your attempt
A. (0)
Concept
(B) is empty, so no second component is available and no pair is formed. Since count is asked, write (0).
Why this answer is correct
The correct answer is A. (0). (B) is empty, so no second component is available and no pair is formed. Since count is asked, write (0).
Exam Tip
(B) खाली है, इसलिए कोई दूसरा घटक नहीं मिलेगा और कोई युग्म नहीं बनेगा। संख्या पूछी गई है, इसलिए (0) लिखें।
