The formal definition of "probability" in statistics is:The appearance of truth a statement or event bears in the light of presentevidenceChance, hap, or luck, regarded as a cause of events and changes in people's affairsA number measuring deviation from expectation in future eventsThe degree at which an event is lacking any obvious principle of organizationThe proportion of times an event occurs when the experiment is repeatedindependently, indefinitely

Virtually any process can be improved by use of statistics, including the law. A much publicized case that involved a debate about probability was the Collins case, which began in 1964. An incident of purse snatching in the Los Angeles area led to the arrest of Michael and Janet Collins. At their trial, an "expert" presented the probabilities listed in table below on characteristics possessed by a couple seen running from the crime scene: Characteristics Probability Man with beard 1/10 Blond woman 1/4 1/10 Yellow car Woman with ponytail Man with moustache Interracial couple 1/10 1/3 1/1000 The chance that a couple had all these characteristics together is 1 in 12 million. Because the Collinses had these characteristics, the Collinses must be guilty. Do yo see any problem with this line of reasoning? Hint: The question of interest is not "what is the probability of finding a couple with these characteristics?" because one such couple has been found (the Collinses), the question is "what…
