**The number of students needed to ensure that outcome from a classroom setting.**

If an exam is graded from 0 to 100, how many students must be enrolled in the class to ensure that at least two students will receive the same grade? As evidence, consider the pigeonhole principle: principle, there should be at least 102 learners participating.

Must there be at least two people in a group of 700 with the same first and last names? Why? Yes.

**If you want to demonstrate the pigeonhole principle, how do you do it?**

The pigeonhole principle states that if k is a positive integer and k 1 objects are placed into k boxes, then exactly one of the boxes must contain two or more objects. A proof by contraposition is used to demonstrate this. Let’s pretend there is only one object in each of the k boxes. As a result, there would be no more than k objects in total.
