What is an arrangement of a specific number of a set of objects in a specific order called?

The correct term for an arrangement of a specific number of a set of objects in a specific order is "permutation." In mathematics and combinatorics, a permutation refers to the different ways in which a subset of items can be arranged or ordered. This concept is important in various fields such as probability, statistics, and computer science, as it helps to determine the number of unique arrangements possible when the order of selection matters.

In contrast, a combination involves selecting items from a set without regard to the order of arrangement, which is different from a permutation where the focus is on the sequence. The terms arrangement and configuration are more general and do not specifically convey the mathematical principle of ordering, making them unsuitable as answers in this context. Thus, understanding that permutations deal explicitly with ordered arrangements is key to grasping why this term is the correct answer.
