Answer: There are 1820 ways that a committee of 4 people can be formed from the 16 members of the ski club.
Step-by-step explanation: The number of ways that a committee of 4 people can be formed from the 16 members of the ski club is given by the combination formula:
C(16, 4) = 16! / (4! * (16 - 4)!) = (16 * 15 * 14 * 13) / (4 * 3 * 2 * 1) = 1820
Therefore, there are 1820 ways that a committee of 4 people can be formed from the 16 members of the ski club.
