Query: There are better alternatives to this.

The bad part is that I had to buy this book for my Probability course, and I will probably end up throwing it away after the course ends. There are exercises in each chapter I have covered so far which have little to do with the material in the chapter. I have also found material which is introduced with little or no continuity. The language is rigid, and the flow of thought is not linear. Overall, it makes the learning experience less efficient, and more frustrating; it increases the load on the student, who is forced to make the connections himself, instead of presenting them in the text, as appropriate, or introducing them via exercises which connect with the current chapter material.The good part is that there are books out there which, in my personal opinion, and using my understand-o-meter, are much better.
