经典概率教科书。核心基础理论，我喜欢读学科领袖写的老书。

Gnedenko was a Soviet mathematician and a student of Kolmogorov. He is perhaps best known for his work with Kolmogorov, and his contributions to the study of probability theory, such as the Fisher-Tippett-Gnedenko theorem. He was a leading member of the Russian school of probability theory and statistics. He also worked on applications of statistics to reliability and quality control in manufacturing. This is perhaps Gnedenko's most famous book and first appeared in Russian in 1950. Written in a clear and concise manner, the book was very successful in providing a first introduction to probability and statistics.
