(6) विद्यार्थियों को (8) अलग-अलग कुर्सियों पर कितने तरीकों से बैठाया जा सकता है?
In how many ways can (6) students be seated on (8) distinct chairs?
Explanation opens after your attempt
A. (20160)
Concept
The chairs are distinct and (6) students are seated, so \(^{8}P_6=20160\). In exams, permutation may apply even when some places remain empty.
Why this answer is correct
The correct answer is A. (20160). The chairs are distinct and (6) students are seated, so \(^{8}P_6=20160\). In exams, permutation may apply even when some places remain empty.
Exam Tip
कुर्सियां अलग हैं और (6) विद्यार्थी बैठेंगे, इसलिए \(^{8}P_6=20160\)। परीक्षा में खाली स्थानों के बावजूद permutation लग सकता है।
