Question

You have 5 reindeer, Jebediah, Ezekiel, Quentin, Lancer, and Gloopin, and you want to have 4 fly your sleigh. You always have your reindeer fly in a single-file line. How many different ways can you arrange your reindeer?

Answer 1

Answer: There are 120 different ways we can arrange reindeer.

Step-by-step explanation:

Since we have given that

Number of reindeer = 5

Number of them fly their sleigh = 4

We need to find the number of different ways we can arrange their reindeer .

For this we will use "Permutation":

here, n = 5

r = 4

So, it becomes,

$^nP_r=\frac{n!}{(n-r)!}\\\\So,\\\\^5P_4=\frac{5!}{(5-4)!}\\\\^5P_4=120$

Hence, there are 120 different ways we can arrange reindeer.
