Explanation opens after your attempt
A. (360)
Concept
The chairs are distinct and (4) students are seated, so \(^{6}P_4=360\). In exams, account for unused chairs carefully.
Why this answer is correct
The correct answer is A. (360). The chairs are distinct and (4) students are seated, so \(^{6}P_4=360\). In exams, account for unused chairs carefully.
Exam Tip
पहले कुर्सियां अलग हैं और (4) विद्यार्थी बैठेंगे, इसलिए \(^{6}P_4=360\)। परीक्षा में खाली कुर्सियों को भी ध्यान में रखें।
