This math topic focuses on calculating permutations, particularly how to order 5 cards with one repeated card, using factorial concepts. It enhances skills in setting up factorial equations to determine the number of distinct ways to arrange a given set of items where order matters and when there are repetitions. The problems present mathematical expression options and students must select the correct formulation to represent the permutations possible under specified conditions. Overall, it aims to provide practice in probability calculations using permutation principles, part of a broader unit on probability and statistics.
