Answer:

60 different ways

Step-by-step explanation:

According to the given data, we have

Number of reindeer i.e 5

Number of them fly their sleigh i.e 3

In order to find  different ways can you arrange your reindeer, we will use "Permutation":

considering, n = 5 and r=3

it becomes,

5P3= 60 (by using calculator)

OR

[tex]nPr = \frac{n!}{(n-r)!}[/tex]

5P3 = 5!/ (5-3)!

5P3=120 / 2

5P3= 60

Thus, ways can you arrange your reindeer in 60 different ways
