This math topic explores the concept of probability through the context of ordering four letter tiles with two repeated letters, emphasizing the use of multiplication to determine the number of distinct arrangements. Each problem presents a situation where students have to calculate permutations where repetition of certain elements (letters) occurs, expressing their answers using multiplication formulas. This is underpinned by introductory principles of binomial notation in probability and statistics.
