यदि \(^{n}C_{2}+^{n}C_{3}=^{n+1}C_{3}\) है, तो यह पहचान किस नियम पर आधारित है?
If \(^{n}C_{2}+^{n}C_{3}=^{n+1}C_{3}\), this identity is based on which rule?
Explanation opens after your attempt
Correct Answer
B. पास्कल नियमPascal rule
Concept
This is the form \(^{n}C_{r-1}+^{n}C_{r}=^{n+1}C_{r}\). It is called Pascal's rule.
Why this answer is correct
The correct answer is B. पास्कल नियम / Pascal rule. This is the form \(^{n}C_{r-1}+^{n}C_{r}=^{n+1}C_{r}\). It is called Pascal's rule.
Exam Tip
यह \(^{n}C_{r-1}+^{n}C_{r}=^{n+1}C_{r}\) का रूप है। इसे पास्कल नियम कहते हैं।
