यदि (A), (B), (C) के वेन आरेख में केवल \(A\cap B\) में (11), केवल \(B\cap C\) में (13), केवल \(C\cap A\) में (9), और तीनों में (4) हैं, तो (n\(A\cap B\)+n\(B\cap C\)+n\(C\cap A\)) कितना है?
If in the Venn diagram of (A), (B), and (C), only \(A\cap B\) is (11), only \(B\cap C\) is (13), only \(C\cap A\) is (9), and all three is (4), what is (n\(A\cap B\)+n\(B\cap C\)+n\(C\cap A\))?
Explanation opens after your attempt
A. (45)
Concept
The pairwise intersection sum is ((11+4)+(13+4)+(9+4)=45). The triple part is included in every pairwise intersection.
Why this answer is correct
The correct answer is A. (45). The pairwise intersection sum is ((11+4)+(13+4)+(9+4)=45). The triple part is included in every pairwise intersection.
Exam Tip
युग्म छेदन योग (=(11+4)+(13+4)+(9+4)=45)। तीनों वाला भाग हर युग्म छेदन में शामिल होता है।
