Probability
Level
4
Santa's nine reindeer Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donner, Blitzen and Rudolph are tired of pulling sleighs all the time so they are going to have a quiz.
One reindeer will be the quiz master and the others will split into four teams of two.
In how many ways can they arrange themselves?
This problem is part of the Advent Calendar 2015.
