There is a great need for a book on introductory probability applied to problems in computing. Probability with R serves as an introduction to probability and its application to computer disciplines and successfully convinces readers of the relevance of probability to computing. Most examples are related to computing and cover a wide range of computer science applications. This thoroughly classroom-tested, self-contained book encourages computing professionals and upper-undergraduates to perform the simulations in R in order to gain a firm understanding of the concepts discussed in the book.
