This math topic focuses on computing the number of distinct ways to order sets of letter tiles, some of which may be repeated. It encourages students to use mathematical expressions to solve permutations and combinations, particularly through the application of factorial calculations often expressed in fraction form. This section introduces students to the fundamentals of probability using combinatorics and factorial notation within the larger context of probability and statistics, specifically introducing binomial notation. Each problem provides an image representing different letter arrangements and multiple-choice answers in the form of mathematical expressions.
