This, like the previous version, is a good collection of the topics needed for a basic undergraduate course or review for a graduate course. An attempt is made to write in a clear and straight-forward style, but there are many passages that appear confusing to uninitiated. Even graduate students have a hard time trying to interpret some of the statements. Also, the author's key examples are sometimes not appropriate, and he often mixes the idea of a sample with sampling from a distribution to obtain a sample of a certain size, by referring to samples of size 1. This is very confusing. I would think that a good re-write could produce an ideal text.
I've found it difficult to use this book, as they often only walk you through one example for how to solve a problem, and then when it comes to the final end-of-chapter questions the problems are exceedingly difficult when compared to the examples they provided. There is little help in transitioning between the two. It is easy to solve simple problems that are dice rolls, because they are simple examples with a small set of outcomes, but it is difficult to take those over-simplified examples and solve the much harder questions at the end.
Similarly, transitions are horrible. Sometimes you turn the page to continue reading and feel like you skipped pages because they take off in another direction with little-to-no lead in.

Also worth noting is I purchased the kindle edition, and it is horrible. It...
Even though the book is supposed to come with a CD with the computer software when you buy it from Amazon the software is not included in the package. Trying to get amazon to ship the CD with the software is a pain as the only way to get them to look at your missing items is to return the book and then have you ship them a new one.....probably going to be missing the software again.
