‘Other applications’ explores the applications of probability theory in less obvious fields, such as law, social science, sport, and economics. Many probability terms are used in a legal sense. Effectively understanding them requires for probabilities to be linked to the real world, and for Bayes' Rule to assess the usefulness of evidence. Anti-doping agencies use probability to assess the risk of false results in testing regimes. Football betting assigns values to teams' strengths to gauge the probability of a result, and judge their accuracy against past predictions. The value of financial investments usually follows a Gaussian distribution. However, this is not always true, and diversifying can reduce risk.
