यदि \(A=\{1,2\}\), \(B=\{3,4\}\), \(C=\{5,6\}\) हैं, तो (\(A\cup B\)\times C) की कार्डिनलिटी क्या है?

If \(A=\{1,2\}\), \(B=\{3,4\}\), \(C=\{5,6\}\), what is the cardinality of (\(A\cup B\)\times C)?

Explanation opens after your attempt
Correct Answer

C. (8)

Step 1

Concept

\(A\cup B={1,2,3,4}\), so (|\(A\cup B\)\times C|=4\cdot2=8). Find the union size first.

Step 2

Why this answer is correct

The correct answer is C. (8). \(A\cup B={1,2,3,4}\), so (|\(A\cup B\)\times C|=4\cdot2=8). Find the union size first.

Step 3

Exam Tip

\(A\cup B={1,2,3,4}\), इसलिए (|\(A\cup B\)\times C|=4\cdot2=8)। पहले संघ की कार्डिनलिटी निकालें।
