यदि \(P=\{0,4,8\}\) और \(Q=\{1\}\) हैं, तो \(P\times Q\) में कितने क्रमित युग्म होंगे?
If \(P=\{0,4,8\}\) and \(Q=\{1\}\), how many ordered pairs are in \(P\times Q\)?
Explanation opens after your attempt
B. (3)
Concept
(n\(P\times Q\)=n(P)n(Q)=3\times 1=3). In counting questions, multiply the number of elements.
Why this answer is correct
The correct answer is B. (3). (n\(P\times Q\)=n(P)n(Q)=3\times 1=3). In counting questions, multiply the number of elements.
Exam Tip
(n\(P\times Q\)=n(P)n(Q)=3\times 1=3)। गिनती वाले प्रश्न में तत्वों की संख्या गुणा करें।
