This math topic focuses on practicing probability by calculating permutations of four-letter words with one letter repeating. Students are asked to determine the number of possible orders for the letters of given words such as "FOOT," "TATT," "BUBB," "PUPP," "MUMM," "TENT," and "SASS." Each problem requires understanding and applying factorial calculations to account for duplicate letters, which is a foundational concept within probability and statistics. This collection of problems helps students improve their ability to handle permutations involving repetitions.
