\(^{9}C_4\times4\) को permutation के रूप में कैसे लिख सकते हैं?
How can \(^{9}C_4\times4\) be written in permutation form?
Explanation opens after your attempt
A. \(^{9}P_4\div3!\)
Concept
One leader is distinct and the order of the other (3) members is irrelevant, so divide \(^{9}P_4\) by (3!). In exams separate roles and ordinary members.
Why this answer is correct
The correct answer is A. \(^{9}P_4\div3!\). One leader is distinct and the order of the other (3) members is irrelevant, so divide \(^{9}P_4\) by (3!). In exams separate roles and ordinary members.
Exam Tip
एक leader अलग है और बाकी (3) सदस्यों का क्रम महत्वहीन है इसलिए \(^{9}P_4\) को (3!) से भाग देंगे। परीक्षा में roles और ordinary members अलग करें।
