यदि (n(A)=64), (n(B)=53) और (n\(A\cap B\)=22) है, तो (n\(A'\cap B\)) कितना है?
If (n(A)=64), (n(B)=53) and (n\(A\cap B\)=22), then what is (n\(A'\cap B\))?
Explanation opens after your attempt
Correct Answer
A. (31)
Concept
\(A'\cap B\) means (B-A), so (53-22=31). View it as the only (B) region.
Why this answer is correct
The correct answer is A. (31). \(A'\cap B\) means (B-A), so (53-22=31). View it as the only (B) region.
Exam Tip
\(A'\cap B\) का अर्थ (B-A) है, इसलिए (53-22=31) है। इसे केवल (B) वाले क्षेत्र की तरह देखें।
