Courses on Chance ``We do not intend for Chance to replace an introductory statistics or probability course; its aim is rather to encourage students to think more rationally about chance events and to make them more informed readers of the daily press. Of course, we do hope it will also encourage the students to continue their study of statistics and probability, either informally or in future courses. In our pilot versions, we have assumed only high school mathematics as a prerequisite.''
