This math topic focuses on understanding and applying the "n choose m" (nCm) formula in probability and statistics, specifically using factorials to determine values. It involves calculating expressions related to combinations, which represent the number of ways to choose a subset of items from a larger set without regard to the order of selection. The skills practiced include simplifying factorial expressions and selecting the correct calculated values from multiple options, enhancing students' ability to manipulate and solve combinatorial and factorial problems efficiently.
