Durrett 09年新书《Elementary Probability》，是econfarmer推荐的《 Essentials of Probability》的第二版升级版。
        原文介绍如下“About 15 years ago, I wrote the book Essentials of Probability, which was designed for a one-semester course in probability that was taken by math majors and students from other departments. This book is, in some sense, the second edition of that book, but there are several important changes:Chapter 1 quickly introduces the notions of independence, distribution, and expected value, which previously made their entrance in Chapters 2, 3, and 4.This makes it easier to discuss examples; for example, we can now talk about the expected value of bets.”
