Question

Use the permutation formula below to find the number of outcomes when n = 10 and r = 6.

Answer 1

151200

Explanation:

A permutation is a mathematical calculation of the number of ways a particular set can be arranged where order matters.

Plug into the permutation formula to solve.

`(n!)/((n-r)!)`

`(10!)/((10-6)!)`

`(10!)/(4!)`

10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

/4 x 3 x 2 x 1

=

10 x 9 x 8 x 7 x 6 x 5

151200
