This math unit initiates with foundational concepts in permutations, focusing on calculating various arrangements of distinct and repeating elements, exemplified through problems involving cards and letters. Initially, students learn to calculate permutations of five items with one repeating, using factorial operations. Over time, complexity increases as they tackle permutations with two repeating items and apply similar principles to scenarios involving four items. Subsequently, the unit explores binomial notation and combinations in depth, advancing from simple calculations of permutations to understanding and interpreting the `nCm` (binomial coefficient) notation. This progression is evident as the unit starts from specific permutation calculations and factorial expressions towards broader combinatorial principles and calculations. Students learn to choose subsets of items and understand the distinctions between permutations and combinations, culminating in the ability to calculate, interpret, and apply these principles in various probabilistic contexts.
