यदि \(A=\{1,2,3\}\), \(B=\{4,5\}\) और \(C=\{6,7,8\}\) हैं, तो \(|A\times B\times C|\) का मान क्या होगा?
If \(A=\{1,2,3\}\), \(B=\{4,5\}\), and \(C=\{6,7,8\}\), what is \(|A\times B\times C|\)?
Explanation opens after your attempt
C. (18)
Concept
For product of three sets, the cardinality is \(3\cdot2\cdot3=18\). For ordered triples, multiply the sizes of all sets.
Why this answer is correct
The correct answer is C. (18). For product of three sets, the cardinality is \(3\cdot2\cdot3=18\). For ordered triples, multiply the sizes of all sets.
Exam Tip
तीन समुच्चयों के गुणनफल में कार्डिनलिटी \(3\cdot2\cdot3=18\) होती है। क्रमित त्रिक में सभी समुच्चयों के आकार गुणा करें।
