\(^{10}C_4\) को एक fixed object method से लिखने पर कौन-सा decomposition सही है?
Using the fixed object method which decomposition of \(^{10}C_4\) is correct?
Explanation opens after your attempt
A. \(^{9}C_4+^{9}C_3\)
Concept
Including or excluding one fixed object gives \(^{9}C_3\) and \(^{9}C_4\). In exams the upper index decreases by (1) in a Pascal split.
Why this answer is correct
The correct answer is A. \(^{9}C_4+^{9}C_3\). Including or excluding one fixed object gives \(^{9}C_3\) and \(^{9}C_4\). In exams the upper index decreases by (1) in a Pascal split.
Exam Tip
एक fixed object को include या exclude करने से \(^{9}C_3\) और \(^{9}C_4\) मिलते हैं। परीक्षा में Pascal split में upper index (1) घटता है।
