यदि \(A=\{1,2\}\), \(B=\{0,3\}\) और \(C=\{5\}\) हैं, तो (n\(A\times B\times C\)) कितना होगा?
If \(A=\{1,2\}\), \(B=\{0,3\}\), and \(C=\{5\}\), what is (n\(A\times B\times C\))?
Explanation opens after your attempt
Correct Answer
B. (4)
Concept
For the product of three sets, the count is (n(A)n(B)n(C)). Therefore, \(2\times 2\times 1=4\).
Why this answer is correct
The correct answer is B. (4). For the product of three sets, the count is (n(A)n(B)n(C)). Therefore, \(2\times 2\times 1=4\).
Exam Tip
तीन समुच्चयों के गुणन में संख्या (n(A)n(B)n(C)) होती है। इसलिए \(2\times 2\times 1=4\)।
