Question

Which of the following is a correct representation for permutation of $10$ objects taken $6$ at a time

• A. ${}_{10}{P}_6$
• B. ${}_{10}^{6}P$
• C. ${}^6{P}_{10}$
• D. ${}_{10}{P}^4$

Answer 1

The correct option is A ${}_{10}{P}_6$

Permutation of $10$ objects taken $6$ at a time is represented by
${}_{10}{P}_6$ or ${}_6^{10}P$ or ${}^{10}{P}_6$ or $P(10,6)$
