Each section starts with problems, so the student has a chance to solve them without help before proceeding. The text then includes solutions to these problems, through which counting and probability techniques are taught. Important facts and powerful problem solving approaches are highlighted throughout the text. In addition to the instructional material, the book contains over 650 problems. The solutions manual contains full solutions to all of the problems, not just answers. Text ISBN: 978-1-934124-06-2 Solutions ISBN: 978-1-934124-07-9
