यदि \(A=\{0,1\}\) और \(B=\{1,2,3\}\) हैं, तो \(A\times B\) के कितने उपसमुच्चय होंगे?
If \(A=\{0,1\}\) and \(B=\{1,2,3\}\), how many subsets does \(A\times B\) have?
Explanation opens after your attempt
Correct Answer
A. \(2^6\)
Concept
(n\(A\times B\)=2\times3=6), so the number of subsets is \(2^6\). Use the formula \(2^n\) for counting subsets.
Why this answer is correct
The correct answer is A. \(2^6\). (n\(A\times B\)=2\times3=6), so the number of subsets is \(2^6\). Use the formula \(2^n\) for counting subsets.
Exam Tip
(n\(A\times B\)=2\times3=6), इसलिए उपसमुच्चयों की संख्या \(2^6\) है। उपसमुच्चय गिनने में \(2^n\) सूत्र लगाएं।
