Download Introduction to Probability by Mark Daniel Ward and Ellen Gundlach


We want to briefly justify why there should be another probability book, when so many others are available. Motivation: Students from majors in the mathematical sciences and in other areas will be more engaged with the material if they are studying problems that are relevant to them. While testing drafts of the book in the classroom, the students who used this book were asked to contribute questions. As a result, many of the exercises in this text began with questions motivated by the students’ own interests. Example- and exercise-oriented approach: Our book serves as a student’s first introduction to probability theory, so we devote significant attention to a wealth of exercises and examples. We encourage students to practice their skills by solving lots of questions. Our exercises are split into practice, extensions, and advanced types of questions. We recommend assigning a small number of questions to students on a daily basis. This promotes more interactive discussion in class between the students and the instructor. It consistently empowers the students to try their hand at some problems of their own. It reduces stress and “cramming” at exam time, as the students consistently develop their understanding during the course. It also provides a firm foundation for the students’ long term understanding of probability. The exercises, theorems, definitions, and remarks are all numbered in one list (instead of numbered separately) because we believe that they all should be used in tandem to understand the chapter material.
