"Mor Harchol-Balter's new book does a beautiful job of introducing students to probability! The book is full of great computer science-relevant examples, wonderful intuition, simple and clear explanations, and mathematical rigor. I love the question-answer style she uses, and could see using this book for students ranging from undergraduate students with zero prior exposure to probability all the way to graduate students (or researchers of any kind) who need to brush up and significantly deepen (and/or broaden) their knowledge of probability."
