Does math belong in the courtroom?

The video explores the birthday paradox, illustrating how probability can be counterintuitive. It discusses the use of statistics in legal cases, highlighting potential misuses and the importance of correct application. Historical and modern cases, including forgery and DNA profiling, are examined to show how statistical analysis can influence court decisions. The video emphasizes the need for careful interpretation of statistical data, especially in legal contexts.
