Perm
Calculate the permutation: 10P4
Expand Hint
The number of different permutations of "n" distinct objects taken "r" at a time is:
$$$P_{(n,r)}=\frac{n!}{(n-r)!}$$$
Hint 2
Permutation format:
$$nPr$$
The number of different permutations of "n" distinct objects taken "r" at a time is:
$$$P_{(n,r)}=\frac{n!}{(n-r)!}$$$
Solving the permutation:
$$$P_{(10,4)}=\frac{10!}{(10-4)!}=\frac{10!}{6!}=\frac{10\cdot 9\cdot 8\cdot 7\cdot 6!}{6!}=5,040$$$
5,040
