High School Need help in permutations and combinations

Click For Summary
Permutations involve arrangements where the order of items is significant, while combinations focus on selections where order does not matter. To quickly identify whether to use permutations or combinations, consider if the sequence of items is important for the problem at hand. If the arrangement affects the outcome, use permutations; if not, use combinations. Resources like Math is Fun provide clear explanations and examples to help clarify these concepts. Understanding this distinction is crucial for solving related mathematical problems effectively.

One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
