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
B. (12)
Concept
\(B\cup C={2,3,4,5}\), so (|A\times\(B\cup C\)|=3\cdot4=12). Find the union first, then multiply.
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.
Exam Tip
\(B\cup C={2,3,4,5}\), इसलिए (|A\times\(B\cup C\)|=3\cdot4=12)। पहले संघ निकालें फिर गुणा करें।
