This topic focuses on solving probability problems related to the number of distinct orders for spelling words with repeated letters. Students practice calculating permutations of letters where one or more letters repeat using factorial mathematics, expressed as multiplication problems. Each problem provides the name spelled with tiles, and the students must determine the various ways these can be arranged. Each problem generates multiple choice answers expressed in LaTeX format for evaluation. This is part of a broader unit on probability and statistics involving factorials.
