Since the order is important, as there are different roles, a permutation is used, hence option B is correct.
When to use the combination and the permutation formula?
- If the order in which the options are taken is important, permutation is used.
- Otherwise, if the order in which the options are taken is not important, combination is used.
In this problem:
- If the order is LeBron and Giannis, LeBron is the co-captain and Giannis is the captain.
- If it is Giannis and LeBron, Giannis is the co-captain and LeBron is the captain.
Hence the order is important, which means that it is a permutation.
