This math topic focuses on computing factorial expressions, specifically those in the form of "1 over a bracketed term factorial." It is an introductory topic within the broader unit on Probability and Statistics related to Factorials. The problems involve evaluating expressions where the factorial notation, denoted as "!", is used after subtracting two numbers within a bracket. The students are presented with multiple-choice questions where they must select the correct value of the factorial expression. These exercises help in understanding the concept of factorials and their computation, which are important in probability calculations and combinatorics.
