यदि (n\(A\cup B\)=n(A)+n(B)) है, तो वेन आरेख में (A) और (B) के बारे में सही निष्कर्ष क्या है?
If (n\(A\cup B\)=n(A)+n(B)), what is the correct conclusion about (A) and (B) in a Venn diagram?
Explanation opens after your attempt
Correct Answer
A. \(A\cap B=\varnothing\)
Concept
In the general formula, the intersection is subtracted, so equality holds only when (n\(A\cap B\)=0). This means the sets are disjoint.
Why this answer is correct
The correct answer is A. \(A\cap B=\varnothing\). In the general formula, the intersection is subtracted, so equality holds only when (n\(A\cap B\)=0). This means the sets are disjoint.
Exam Tip
सामान्य सूत्र में छेदन घटता है, इसलिए बराबरी तभी होगी जब (n\(A\cap B\)=0)। इसका अर्थ असंबद्ध समुच्चय है।
