यदि \(A=\{1,2,3\}\), \(B=\{1,2,3\}\) और \(R=\{(a,b)\in A\times B:a+b=4\}\), तो (R) क्या है?
If \(A=\{1,2,3\}\), \(B=\{1,2,3\}\), and \(R=\{(a,b)\in A\times B:a+b=4\}\), what is (R)?
Explanation opens after your attempt
Correct Answer
A. ({(1,3),(2,2),(3,1)})
Concept
All ordered pairs with sum (4) are ((1,3),(2,2),(3,1)). A relation is a subset of \(A\times B\).
Why this answer is correct
The correct answer is A. ({(1,3),(2,2),(3,1)}). All ordered pairs with sum (4) are ((1,3),(2,2),(3,1)). A relation is a subset of \(A\times B\).
Exam Tip
योग (4) देने वाले सभी क्रमित युग्म ((1,3),(2,2),(3,1)) हैं। संबंध \(A\times B\) का उपसमुच्चय होता है।
