Final answer:

Permutations involve ordered arrangements with unique items, while combinations involve selection without order. Understanding these concepts is crucial for solving arrangement and selection problems.


Explanation:

Permutations refer to ordered arrangements where each item is unique, while combinations involve selection without regard to the order. Understanding the difference is essential for solving problems involving arranging or selecting items.

Permutations involve factorial calculations to determine the total number of arrangements, while combinations use formulas that account for selections without order.

For Sara's passcode, since she can't repeat numbers and order matters, it involves permutations. The team formation and pizza topping selection questions involve combinations due to the focus on selection without order.
