वेन आरेख में केवल (A) वाला क्षेत्र किससे लिखा जाता है?
In a Venn diagram, how is the region only in (A) written?
Explanation opens after your attempt
Correct Answer
B. (A-B)
Concept
Only (A) contains elements that are in (A) but not in (B), so the region is (A-B). It can also be written as \(A\cap B'\).
Why this answer is correct
The correct answer is B. (A-B). Only (A) contains elements that are in (A) but not in (B), so the region is (A-B). It can also be written as \(A\cap B'\).
Exam Tip
केवल (A) में वे अवयव होते हैं जो (A) में हैं पर (B) में नहीं हैं, इसलिए क्षेत्र (A-B) है। इसे \(A\cap B'\) भी लिख सकते हैं।
