A much-quoted classical work. Few writers on probability are quoted more often than Bertrand--and with good reason. He is clear and to the point. His eyes are open clearly to the traps and pitfalls of his subject and he is able to open his readers' eyes as well. And he is immensely readable. Simple and direct ... everywhere common sense and mother wit ... and conspicuously displayed. E. W. Davis
