This math topic covers permutations involving repeating elements, focusing on calculating the number of ways to arrange four-letter sequences with two repeating letters using factorial equations. It delves into practical examples like arranging the letters in words such as "COCO," "NOON," "MAMA," and "PEEP." Each question requires students to express the arrangements as factorial expressions and provides multiple answer choices, reinforcing understanding of the factorial concepts and permutation calculations in probability and statistics.
