Ariel wants to choose 5 players for her basketball team. There are 7 players to choose from. How many different teams can Ariel make?
A. 21
B. 32
C. 42
D. 56
D. 56
To find the number of different teams that Ariel can make, we need to use the combination formula.
The number of ways to choose 5 players from a group of 7 is given by the formula:
C(7, 5) = 7! / (5! * (7-5)!) = 7! / (5! * 2!) = (7 * 6 * 5!) / (5! * 2 * 1) = (7 * 6) / (2 * 1) = 42 / 2 = 21
Therefore, Ariel can make 21 different teams.
The correct answer is A. 21.
