I am doing an introductory Probability course this semester and the textbook we are set to use is 'A first course in Probability' by Sheldon Ross. However, upon reading reviews from amazon and elsewhere, it appears this book is not that helpful and 'is the WORST book I have ever used' and 'the examples don't help you do the problems' are some quotes used. The average grading was 2.9 out of 5. I am wondering therefore if anybody who has done an introductory probability course could recommend any textbooks that they thought were useful during their study. I might consider the book by Schaum but I am not entirely sure if this is at the right level. Does anybody have any suggestions? Many thanks.
