If \(U=\{red,blue,green\}\) and \(A=\{red\}\), which is (A')?
Explanation opens after your attempt
B. ({नीला,हरा})({blue,green})
Concept
(A') contains the colors in (U) that are not in (A). So blue and green are correct.
Why this answer is correct
The correct answer is B. ({नीला,हरा}) / ({blue,green}). (A') contains the colors in (U) that are not in (A). So blue and green are correct.
Exam Tip
(A') में (U) के वे रंग होंगे जो (A) में नहीं हैं। इसलिए नीला और हरा सही हैं।
