Features: This book is a supplementary textbook written for a wide range of students, aligned with the course requirements. It aims to help students fully understand, master, and excel in the subject. It is hoped that this book will deepen readers' comprehension of the fundamental concepts of probability theory and mathematical statistics, enabling them to grasp problem-solving methods and techniques. This will achieve the goal of reviewing and consolidating teaching content while cultivating the ability to analyze and solve problems. This book is based on the teaching syllabus of the probability and statistics course and compiled from the author's years of teaching experience. The book consists of 8 chapters, covering topics such as random events and probability, random variables and probability distributions, multivariate random variables and their probability distributions, the digital characteristics of random variables, the law of large numbers and the central limit theorem, samples and sampling distributions, parameter estimation, and hypothesis testing. Each chapter is structured as follows: Basic Knowledge Points, which provides a detailed summary of the chapter's key concepts, emphasizing the connection between chapters; and Example Analysis, which includes numerous examples related to the key points, with diverse question types and difficulty levels ranging from basic to advanced. The book includes both simpler fundamental problems and more challenging postgraduate entrance examination simulation questions. In particular, a large number of postgraduate entrance examination questions are selected for detailed analysis. Typical examples are explained from different perspectives and with multiple methods, focusing on the understanding of basic concepts, training in various types of fundamental problems, and the development of comprehensive problem-solving skills. This book can serve as a supplementary textbook or reference book for undergraduate students in engineering and science disciplines of higher education institutions taking the probability theory and mathematical statistics course. It is also suitable for postgraduate entrance examination candidates for reference.
