(n) distinct objects की circular arrangements में ((n-1)!) को (n!) से derive करने का सही कारण क्या है?
What is the correct reason for deriving ((n-1)!) from (n!) for circular arrangements of (n) distinct objects?
Explanation opens after your attempt
A. हर circular arrangement (n) rotations से linear arrangements में गिनी जाती हैEach circular arrangement is counted as (n) rotations in linear arrangements
Concept
Rotations are duplicates in the linear count (n!). In exams divide rotational overcount by (n) in circular arrangements.
Why this answer is correct
The correct answer is A. हर circular arrangement (n) rotations से linear arrangements में गिनी जाती है / Each circular arrangement is counted as (n) rotations in linear arrangements. Rotations are duplicates in the linear count (n!). In exams divide rotational overcount by (n) in circular arrangements.
Exam Tip
Linear (n!) count में rotations duplicate होते हैं। परीक्षा में circular arrangement में rotational overcount को (n) से divide करें।
