This book is an outgrowth of lectures on the theory of probability which the author has given at Stanford University for several years. At first a short mimeographed text covering only the elementary parts of the subject was used for the guidance of students. As time went on and the scope of the course was gradually enlarged, the necessity arose of putting into the hands of students a more elaborate exposition of the most important parts of the theory of probability. Accordingly, a rather large manuscript was prepared for this purpose. The author did not plan at first to publish it, but students and other persons who had opportunity to peruse the manuscript were so persuasive that publication was finally arranged.
