यदि \(P=\{3,6,9\}\) और \(Q=\{0,1\}\) हैं, तो (n\(P\times Q\)) कितना होगा?
If \(P=\{3,6,9\}\) and \(Q=\{0,1\}\), what is (n\(P\times Q\))?
Explanation opens after your attempt
C. (6)
Concept
(n\(P\times Q\)=n(P)n(Q)=3\times 2=6). To find the number in Cartesian product, multiply.
Why this answer is correct
The correct answer is C. (6). (n\(P\times Q\)=n(P)n(Q)=3\times 2=6). To find the number in Cartesian product, multiply.
Exam Tip
(n\(P\times Q\)=n(P)n(Q)=3\times 2=6)। कार्तीय गुणन में संख्या निकालने के लिए गुणा करें।
