यदि \(A=\{0,1,2\}\) और \(B=\{0,1,2,3\}\), तो \(A\times B\) में कितने युग्म ((a,b)) ऐसे हैं जिनमें (a+b<3) है?
If \(A=\{0,1,2\}\) and \(B=\{0,1,2,3\}\), how many pairs ((a,b)) in \(A\times B\) satisfy (a+b<3)?
Explanation opens after your attempt
B. (6)
Concept
For (a=0,1,2), the possible values of (b) are (3,2,1), totaling (6). Read the inequality boundary carefully.
Why this answer is correct
The correct answer is B. (6). For (a=0,1,2), the possible values of (b) are (3,2,1), totaling (6). Read the inequality boundary carefully.
Exam Tip
(a=0,1,2) के लिए (b) के क्रमशः (3,2,1) मान हैं, कुल (6)। असमानता में सीमा को सावधानी से देखें।
