Sheldon Ross's "A First Course in Probability" is recognized for its solid theoretical foundation and practical examples, making it a valuable resource for understanding probability, particularly in engineering contexts. The book has been used in academic settings, providing a working knowledge of the subject. While newer editions exist, including a 9th edition that is only slightly longer than the 3rd, concerns about the high price of the latest edition, at $145, have been raised, suggesting that it may not offer sufficient value compared to earlier versions. Overall, while there may be better options available, Ross's book remains a reasonable choice for those seeking to enhance their probability skills.
