\({}^{n}C_r={}^{n}C_s\) और \(r\neq s\) हो तो generally कौन-सा relation मिलता है?
If \({}^{n}C_r={}^{n}C_s\) and \(r\neq s\), what relation generally follows?
Explanation opens after your attempt
Correct Answer
A. (r+s=n)
Concept
In combination symmetry, unequal equal-values come from complementary indices. In exams check sum (n) for equal combinations.
Why this answer is correct
The correct answer is A. (r+s=n). In combination symmetry, unequal equal-values come from complementary indices. In exams check sum (n) for equal combinations.
Exam Tip
Combination symmetry में unequal equal-values complementary indices से आते हैं। परीक्षा में equal combinations में sum (n) check करें।
