### The pigeonhole principle is one of those simple yet beautiful, widely used theorems with lots of applications. Any high school going kid may understand what the theorem wants to say, yet its beauty baffles and brings excitement in even the most experienced mathematician.

- Lesson 4: The Pigeonhole Principle The Pigeonhole Principle states that if you have X pigeonholes and X + 1 (or more) pigeons, then one pigeonhole must contain more than one pigeon. Sounds simple enough…are you ready to try some more problems? The solutions to the following problems require very little mathematics – but you do have to think a little. Do You Understand? 1.
