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

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

Explanation opens after your attempt
Correct Answer

B. (12)

Step 1

Concept

\(B\cup C={2,3,4,5}\), so (|A\times\(B\cup C\)|=3\cdot4=12). Find the union first, then multiply.

Step 2

Why this answer is correct

The correct answer is B. (12). \(B\cup C={2,3,4,5}\), so (|A\times\(B\cup C\)|=3\cdot4=12). Find the union first, then multiply.

Step 3

Exam Tip

\(B\cup C={2,3,4,5}\), इसलिए (|A\times\(B\cup C\)|=3\cdot4=12)। पहले संघ निकालें फिर गुणा करें।
