6 hockey players want to be either a captain or an assistant. The 1st player chosen will be the captain, and the second will be the assistant.
How many ways can these players be chosen captain and assistant?
Is this a permutation or a combination?
There are 6 ways to choose a captain, and 5 from the remaining players as a assistant.
So there is a total of 6*5=30 ways.
It is a permutation because the order of choice matters.
