This document outlines lessons on permutations and combinations. Lesson 1 covers permutations, including illustrating permutations of objects, deriving the formula for finding the number of permutations of n objects taken r at a time (nPr), and solving problems involving permutations. Lesson 2 covers combinations, including illustrating combinations of n objects, differentiating permutations from combinations of n objects taken r at a time, deriving the formula for finding the number of combinations of n objects taken r at a time, and solving problems involving permutations and combinations.
