For the first two editions of Probability (GTM 95), each chapter included a comprehensive and diverse set of relevant exercises. While the work on the third edition was still in progress, it was decided that it would be more appropriate to publish a separate book that would comprise all of the exercises from previous editions, in addition to many new exercises. Most of the material in this book consists of exercises created by Shiryaev, collected and compiled over the course of many years while working on many interesting topics. Many of the exercises included in the book contain helpful hints and other relevant information. An appendix at the end of the book contains a summary of the main results, notation and terminology from probability theory that are used throughout the present book, as well as additional material from combinatorics, potential theory and markov chains.
