A class of 13 students is trying to decide how they should form themselves into groups of 4 for an upcomiing classroom activity. One of the students first proposes they calculate how many combinations of 4 students can be made from 13 people. After doing the calculations, how many groups of 4 people can be made from a student population of 13 people?
