This math topic focuses on calculating the number of possible arrangements of letter tiles when some letters are repeated. Specifically, it delves into the ways to order 4-letter words with 2 repeating letters, employing foundational concepts in probability and binomial notation. The sample words discussed include 'MAMA', 'PEEP', 'NOON', and 'COCO', each examining distinct scenarios of repeat letters. This forms a part of learning about probability and statistics within the introduction to binomial notation.
