This course challenges students to recognize the ubiquity of probability and risk in their daily lives. The theme of stochasicity is explored through the perspectives of economists, psychologists, investors, entrepreneurs, political scientists, biologists, and of course mathematicians. Students are asked to explore critically the institutions, both formal and informal, which have developed to deal with risk and uncertainty in society. The concept of evidence in law and science is examined. Students also investigate the ways in which we perceive and respond to probability in the world around us.
