Six. If you prefer math, you can calculate it as 4 combination 2

4! / (2!)^2
24 / 4 = 6

Or you can work it out manually:

1. Blue Red
2. Blue Yellow
3. Blue Orange
4. Red Yellow
5. Red Orange
6. Yellow Orange

Four different-colored balls are being used in a gym class activity – blue, red, yellow and orange. Each student must hold two different-colored balls, but no two students can have the same two colors (for example, only one student can hold the blue and red ball).

How many students can play the game?
