Core Permutation, Combination, and Probability

Permutation, combination, and probability are often the most challenging topics in quantitative reasoning, requiring precision and systematic thinking. This course provides a rigorous, step-by-step introduction to these essential mathematical concepts. You will gain the foundational knowledge and structured problem-solving techniques needed to tackle complex counting and chance problems found on high-stakes standardized tests. What you'll learn: * Learn the fundamental counting principles, factorials, and the clear distinction between permutations and combinations. * Master formula application for permutations with and without repetition, including circular arrangements. * Understand the core rules of probability, conditional probability, and how to analyze independent and dependent events. * Apply systematic methods to break down complex word problems and correctly identify constraints and conditions. * Practice solving various common problem types encountered in competitive quantitative examinations. The course begins with foundational concepts and definitions, gradually progressing through complex counting techniques before introducing the principles of probability theory. Each section includes detailed written explanations and exercises to solidify understanding. This course is designed for absolute beginners or those who need a thorough review of combinatorics and probability for standardized tests requiring quantitative skills.
