यदि \(A=\{1,2,3\}\), \(B=\{4,5\}\) और \(C=\{6,7\}\) हैं, तो (|\(A\times B\)\times C|) क्या है?
If \(A=\{1,2,3\}\), \(B=\{4,5\}\), and \(C=\{6,7\}\), what is (|\(A\times B\)\times C|)?

Correct Answer
C. (12)
Concept
\(|A\times B|=3\cdot2=6\), and then \(6\cdot2=12\). Cardinality still multiplies in nested products.
Why this answer is correct
The correct answer is C. (12). \(|A\times B|=3\cdot2=6\), and then \(6\cdot2=12\). Cardinality still multiplies in nested products.
Exam Tip
\(|A\times B|=3\cdot2=6\) और फिर \(6\cdot2=12\)। नेस्टेड गुणनफल में भी कार्डिनलिटी गुणा होती है।
