This “tried and true” text offers extremely readable coverage of the principles of finite mathematics and their applications in business, social science, and the life sciences. The book divides naturally into four parts. The first part consists of linear mathematics: linear equations, matrices, and linear programming (chapters 1-4); the second part is devoted to probability and statistics (chapter 5-7); the third covers topics utilizing the ideas of the first two parts (chapters 8-10); and the fourth covers topics from discrete mathematics sometimes included in the modern finite mathematics curriculum. In revising this book, the authors incorporated a wide range of topics from which the instructor may design a curriculum, as well as a high degree of flexibility in the order in which the topics may be presented.
