\(^{8}C_3\times3\) को सीधे किस permutation relation से भी समझ सकते हैं?
By which permutation relation can \(^{8}C_3\times3\) also be understood directly?
Explanation opens after your attempt
C. \(^{8}P_3\div2!\)
Concept
One of the three is distinguished as captain, so removing the order of the remaining (2) members gives \(^{8}P_3\div2!\). In exams reduce overcounting by checking the roles.
Why this answer is correct
The correct answer is C. \(^{8}P_3\div2!\). One of the three is distinguished as captain, so removing the order of the remaining (2) members gives \(^{8}P_3\div2!\). In exams reduce overcounting by checking the roles.
Exam Tip
तीन में से एक captain distinguished है इसलिए बाकी (2) members का order हटाने पर \(^{8}P_3\div2!\) मिलता है। परीक्षा में roles की संख्या देखकर overcounting घटाएँ।
