I am a college student taking Probability (2 credit course) and our teacher used this book. I must say that this book is one of the worst books I have ever worked from. The material in the sections is all over the place, and the examples are blended in with the material so you really don't know what's going on. The fact of the matter is, the subject matter in this book isn't very complicated. However, the god-awful examples and the lack of clear and concise explanations really drives you insane. Not recommended at all.
