Answer to Problem 13CFU
The number of different ways to arrange10 students in a roware
Explanation of Solution
Given information:
The number of students in a group are 10.
Formula used:
If there are n objects taken n at a time then permutation is defined as
Calculation:
Consider the provided information that number of students in a group are 10.
To arrange 10 students in a row, there are 10 ways to make sit a student at first place then 9 ways toarrange at second place, 8 ways to arrange at third place and so on.
Therefore, number of ways are
Recall that if there are n objects taken n at a time then permutation is defined as
Here n is 10.
Thus, the number of different ways to arrange 10 students in a row are
