Introduction to Probability Theory and Stochastic Processes

Understanding randomness and uncertainty is crucial for modern data analysis, engineering, and decision-making. This text-based course demystifies the mathematical frameworks used to model random events and systems that evolve over time. You will transition from basic intuitive probability to building a solid mathematical foundation in random variables, distribution functions, and stochastic processes. Through clear written explanations and step-by-step mathematical derivations, you will learn how to model uncertainty and analyze dynamic systems. What you'll learn: - Understand the fundamental laws of probability, conditional probability, and Bayes' theorem. - Analyze discrete and continuous random variables, their probability distributions, and key statistical properties. - Explore joint distributions, covariance, and the limit theorems that underpin modern data science. - Master the core concepts of stochastic processes, including Markov chains and random walks. - Apply probability models to real-world scenarios, such as queueing systems and algorithmic decision-making. The journey begins with foundational definitions of probability space and set theory before moving into advanced random variables. You will then progress to stochastic processes, exploring how system states change over time through structured text-based lessons and practice problems. This course is designed for beginners, students, and aspiring data professionals who want a clear, mathematically sound introduction to probability without needing prior advanced coursework.
