* For the first role, there are 10 choices.
* For the second role, there are 9 people left, so 9 choices.
* For the third role, there are 8 choices.
* For the fourth role, there are 7 choices.
* For the fifth role, there are 6 choices.
To find the total number of different ways to assign the roles, we multiply the number of choices at each step:
10 * 9 * 8 * 7 * 6 = 30,240
There are 30,240 different ways to assign the 5 roles to the 10 people.
