Probability and Random Variables for IIT-JAM Prep

Mastering the mathematical foundations of random variables is the single most critical step to scoring high in competitive statistics exams. This text-based course guides you step-by-step through the core theory and analytical techniques required for rigorous mathematical statistics. You will transition from basic probability concepts to solving complex problems involving univariate and bivariate random variables, cumulative distribution functions, and mathematical expectation. What you'll learn: 1. Understand the fundamental definitions of discrete and continuous random variables. 2. Calculate probability mass functions, probability density functions, and cumulative distribution functions. 3. Master mathematical expectation, variance, and moment generating functions. 4. Analyze joint, marginal, and conditional distributions for bivariate random variables. 5. Apply transformation techniques to find the distributions of functions of random variables. 6. Practice exam-style problems with clear, step-by-step written solutions. The course starts with basic probability spaces and core definitions, building up systematically to multi-dimensional distributions and limit theorems. You will learn entirely through structured written explanations, rigorous mathematical derivations, and targeted practice problems designed for exam success. This course is designed for students preparing for the IIT-JAM or similar university-level examinations in mathematics and statistics, requiring only a basic understanding of introductory calculus.
