यदि (n\(A\cup B\)=n(A)+n(B)), तो वेन आरेख के अनुसार कौन सा निष्कर्ष सही है?
If (n\(A\cup B\)=n(A)+n(B)), which conclusion is correct according to the Venn diagram?
Explanation opens after your attempt
A. \(A\cap B=\varnothing\)
Concept
In the union formula, the subtracted part is (n\(A\cap B\)), which must be (0) here. Hence the sets are disjoint.
Why this answer is correct
The correct answer is A. \(A\cap B=\varnothing\). In the union formula, the subtracted part is (n\(A\cap B\)), which must be (0) here. Hence the sets are disjoint.
Exam Tip
संघ सूत्र में घटने वाला भाग (n\(A\cap B\)) है, जो यहां (0) होगा। इसलिए समुच्चय असंबद्ध हैं।
