\(^{n}C_2\) को graph के edges से जोड़ें तो इसका क्या अर्थ है?
If \(^{n}C_2\) is connected with edges of a graph what does it mean?
Explanation opens after your attempt
A. (n) vertices में unordered pair of vertices की संख्याNumber of unordered pairs of vertices among (n) vertices
Concept
An edge is formed by an unordered pair of two vertices. In exams use \(^{n}C_2\) for pairs without direction.
Why this answer is correct
The correct answer is A. (n) vertices में unordered pair of vertices की संख्या / Number of unordered pairs of vertices among (n) vertices. An edge is formed by an unordered pair of two vertices. In exams use \(^{n}C_2\) for pairs without direction.
Exam Tip
एक edge दो vertices के unordered pair से बनता है। परीक्षा में pair without direction के लिए \(^{n}C_2\) लगाएँ।
