(n) distinct objects की circular arrangement में ((n-1)!) क्यों आता है?
Why does ((n-1)!) appear in circular arrangement of (n) distinct objects?
Explanation opens after your attempt
A. एक object को fixed मानकर rotation duplicates हटाए जाते हैंOne object is fixed to remove rotational duplicates
Concept
Rotations in a circle are considered the same so one position is fixed. In exams divide linear (n!) by (n) for circular permutation.
Why this answer is correct
The correct answer is A. एक object को fixed मानकर rotation duplicates हटाए जाते हैं / One object is fixed to remove rotational duplicates. Rotations in a circle are considered the same so one position is fixed. In exams divide linear (n!) by (n) for circular permutation.
Exam Tip
Circle में rotations same माने जाते हैं इसलिए एक position fixed करते हैं। परीक्षा में circular permutation में linear (n!) को (n) से divide करें।
