Answer 2

60 ways.

Explanation:

Total number of Reindeer = 5

We require 3 to fly the sleigh

• 3 reindeer out of 5 can be selected in
  `^(5)C_(3)=10 ways`

The 3 reindeer fly in single line.

Hence they can be arranged in 3!=6 Ways

Total number of arrangement of the reindeer =6 X 10 =60

The reindeer can be arranged in 60 ways.
