यदि \(A=\{11,22\}\) और \(B=\{33,44,55,66\}\) हैं, तो \(A\times B\) में कितने युग्म होंगे?
If \(A=\{11,22\}\) and \(B=\{33,44,55,66\}\), how many pairs are in \(A\times B\)?
Explanation opens after your attempt
C. (8)
Concept
(A) has (2) elements and (B) has (4) elements, so \(2\times 4=8\). Counting elements first is the safest method.
Why this answer is correct
The correct answer is C. (8). (A) has (2) elements and (B) has (4) elements, so \(2\times 4=8\). Counting elements first is the safest method.
Exam Tip
(A) में (2) और (B) में (4) तत्व हैं, इसलिए \(2\times 4=8\)। पहले तत्व गिनना सबसे सुरक्षित तरीका है।
