यदि (|A|=2), (|B|=3) और (|C|=4), तो \(|A\times B\times C|\) क्या होगा?
If (|A|=2), (|B|=3), and (|C|=4), what is \(|A\times B\times C|\)?
Explanation opens after your attempt
C. (24)
Concept
For Cartesian product of three sets, the cardinality is \(2\cdot3\cdot4=24\). For ordered triples, multiply all three sizes.
Why this answer is correct
The correct answer is C. (24). For Cartesian product of three sets, the cardinality is \(2\cdot3\cdot4=24\). For ordered triples, multiply all three sizes.
Exam Tip
तीन समुच्चयों के कार्तीय गुणनफल में कार्डिनलिटी \(2\cdot3\cdot4=24\) है। क्रमित त्रिक के प्रश्न में तीनों आकार गुणा करें।
