यदि \(A=\{1,2,3\}\), \(B=\{2,3,4\}\), \(C=\{1,3,5\}\) हैं, तो (|\(A\cap B\)\times C|) क्या होगा?
If \(A=\{1,2,3\}\), \(B=\{2,3,4\}\), \(C=\{1,3,5\}\), what is (|\(A\cap B\)\times C|)?
Explanation opens after your attempt
Correct Answer
C. (6)
Concept
\(A\cap B={2,3}\) and (|C|=3), so the cardinality is \(2\cdot3=6\). Simplify the intersection first.
Why this answer is correct
The correct answer is C. (6). \(A\cap B={2,3}\) and (|C|=3), so the cardinality is \(2\cdot3=6\). Simplify the intersection first.
Exam Tip
\(A\cap B={2,3}\) और (|C|=3), इसलिए कार्डिनलिटी \(2\cdot3=6\) है। प्रतिच्छेद को पहले सरल करें।
