To find the number of ways 3 students can be arranged in 3 chairs, we can use the concept of permutations.
In permutations, the order of the elements matters. The formula for finding the number of permutations is n! / (n-r)!, where n is the total number of items and r is the number of items to be arranged.
In this case, we have 3 students (n=3) and 3 chairs (r=3). So, the number of ways to arrange them can be calculated as:
3! / (3-3)!
= 3! / 0!
= 3! / 1
= 3 x 2 x 1 / 1
= 6
Therefore, there are 6 different ways to arrange 3 students in 3 chairs.
