Answer 1

Given:-

Nine bands are to perform at a weekend festival.

To find:-

The number of different ways to shedule it.

To find the all possible chances. we use permutation method that is,

since there are 9 bands the total chaces are,

`9!`

By simplifying this value. we get,

`9!\text{ = 9}*8*7*6*5*4*3*2*1`

By furthur simplification. we get,

`9=\text{ 362880}`

So there are totally 362880 different ways.
