यदि \(A=\{0,1,2\}\) और \(B=\{1,2,3\}\) है, तो \(A\times B\) में ऐसे कितने युग्म ((x,y)) हैं जिनके लिए (x<y) है?
If \(A=\{0,1,2\}\) and \(B=\{1,2,3\}\), how many pairs ((x,y)) in \(A\times B\) satisfy (x<y)?
Explanation opens after your attempt
C. (6)
Concept
For (x=0) there are (3) choices, for (x=1) there are (2), and for (x=2) there is (1). Total pairs are (3+2+1=6).
Why this answer is correct
The correct answer is C. (6). For (x=0) there are (3) choices, for (x=1) there are (2), and for (x=2) there is (1). Total pairs are (3+2+1=6).
Exam Tip
(x=0) पर (3), (x=1) पर (2), और (x=2) पर (1) विकल्प हैं। कुल (3+2+1=6) युग्म मिलते हैं।
