You have 555 reindeer, Bloopin, Rudy, Ezekiel, Prancer, and Balthazar, and you want to have 333 fly your sleigh. You always have your reindeer fly in a single-file line.

How many different ways can you arrange your reindeer?

60 combinations for single file.

Step-by-step explanation:

Bloopin has 12 combinations where he leads the single file line of 3 only reindeer's at a time including the reindeer that leads the file. This is not a file of five but as the question asks for 3 there are 5 reindeer's that each have a turn of 12 each, to single file 3 reindeer's, it is here we get 12 for each combination.

12 x 5 = 60 combination.
