Question

Five students are standing in line waiting to enter a club, and they will be allowed to enter in groups of two students. How many combinations of two students are there

Answer 1

There will be 2 groups of 2

Explanation:

2people=1group

5-2=3people

There are 3 people left because two of them went into a group.

3-2=1

There is only one person left and you cant split one person in half so the answer is 2.
