Question

What is true about problem 4 after determining the set of pigeons and the set of pigeonholes according to the Pigeonhole Principle

Answer 1

Step-by-step explanation:

In each case, the sum of the two numbers is 9. These pairs will serve as our "pigeon-holes". If we select 5 distinct integers (i.e., the "pigeons") from the integers 1 to 8, inclusive -- then by the pigeonhole principle, at least two of them must be in the same pair.
