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,
[tex]9![/tex]
By simplifying this value. we get,
[tex]9!\text{ = 9}\times8\times7\times6\times5\times4\times3\times2\times1[/tex]
By furthur simplification. we get,
[tex]9=\text{ 362880}[/tex]
So there are totally 362880 different ways.
