Perm

#571 / Prob & Stats Easy

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
