यदि \(A=\{1,2\}\), \(B=\{3,4,5\}\) और \(C=\{6,7\}\) हैं, तो \(|A\times B\times C|\) का मान क्या होगा?

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

Explanation opens after your attempt
Correct Answer

C. (12)

Step 1

Concept

The cardinality for three sets is \(2\cdot3\cdot2=12\). For ordered triples, multiply all sizes.

Step 2

Why this answer is correct

The correct answer is C. (12). The cardinality for three sets is \(2\cdot3\cdot2=12\). For ordered triples, multiply all sizes.

Step 3

Exam Tip

तीन समुच्चयों में कार्डिनलिटी \(2\cdot3\cdot2=12\) होती है। क्रमित त्रिक में सभी आकार गुणा करें।
