Fault Tree Analysis ExamplesSuppose we visit the courthouse in a certain town, and we observe people who stop at the office of the local justice of the peace to register their marriages. Let A be the independent probability of finding in the office an adult woman who is going to get married (i.e., female spouse), while B is the probability of finding a marrying adult man (i.e., male spouse). We disregard any liaison between staff members who are employed in that office in order to be free of bias in our experiment.
