Understanding Evidence under Bayes' Theorem in Legal Contexts
Definition & meaning
The concept of evidence under Bayes' Theorem involves understanding how the probability of an event changes based on new evidence. Specifically, it examines the likelihood of a person being guilty or not guilty based on the evidence presented. This theorem is rooted in the principle of inverse probability, which helps assess how likely an event is, given certain conditions. Essentially, it allows for a comparison of the probability of observing specific evidence if the accused is guilty versus if they are innocent.

Real-World Examples
Here are a couple of examples of abatement:
In a criminal trial, if a defendant is accused of theft, Bayes' Theorem can be used to evaluate the probability of guilt based on new evidence, such as DNA found at the crime scene. For instance, if the DNA matches the accused, the probability of guilt increases significantly. Conversely, if the DNA does not match, the probability of innocence is strengthened. (Hypothetical example.)
