In the factorial formula of \(^{n}P_r\), the denominator ((n-r)!) is connected with which group of objects?
Explanation opens after your attempt
Correct Answer
A. न चुनी गई वस्तुएँUnchosen objects
Concept
In (n!), internal orders of the unchosen ((n-r)) objects are extra, so they are removed. In exams identify the remaining part in the permutation formula.
Why this answer is correct
The correct answer is A. न चुनी गई वस्तुएँ / Unchosen objects. In (n!), internal orders of the unchosen ((n-r)) objects are extra, so they are removed. In exams identify the remaining part in the permutation formula.
Exam Tip
(n!) में न चुनी गई ((n-r)) वस्तुओं के अंदरूनी क्रम extra हैं इसलिए उन्हें हटाया जाता है। परीक्षा में permutation formula में remaining part पहचानें।
