Unlike most probability textbooks, which are often written only for the mathematically-oriented students, Mark Ward and Ellen Gundlach’s Introduction to Probability makes the subject much more accessible, reaching out to a much wider introductory-level audience. Its approachable and conversational style, highly visual approach, practical examples, and step-by-step problem solving procedures help all kinds of students understand the basics of probability theory and its broad applications in the outside world. This textbook has been extensively class-tested throughout its preliminary edition in order to make it even more effective at building confidence in students who have viable problem-solving potential but are not fully comfortable in the realm of mathematics. Its rich pedagogy, combined with a thoughtful structure, provides an accessible introduction to this complex subject.
