Test X: The message contains certain words (X) Bayes' theorem is a formula that describes how to update the probabilities of hypotheses when given evidence. It follows simply from the axioms of conditional probability, but can be used to powerfully reason about a wide range of problems involving belief updates. To best understand Bayes’ Theorem, also referred to as Bayes’ Rule, I find it helpful to start with a story. In Harry Potter and the Goblet of Fire, the fourth book in the Harry Potter series by J.K. Rowling, the Dark Mark has been released over the Quidditch World cup, and total pandemonium has ensued. Bayes' Theorem is a simple mathematical formula used for calculating conditional probabilities. It figures prominently in subjectivist or Bayesian approaches to epistemology, statistics, and inductive logic.

The theorem was discovered among the papers of the English Presbyterian minister and mathematician Thomas Bayes and published posthumously in 1763.

Bayes’s theorem is written, in mathematical notation, as P(A|B) = (P(B|A)P(A))/P(B). It looks complicated. But you don’t need to worry about what all those symbols mean: it’s fairly easy to Point your mouse at the numbers in the table in order to get an explanation of how they were calculated. The answer to the patient's question also could be computed from Bayes's Theorem: We know that P (Disease)=0.002, P (Screen Positive | Disease)=0.85 and P (Screen Positive)=0.08. Put all the above information in a Venn diagram as shown below. Use Bayes' theorem to write the probability that no aircraft is present in the range of the radar given that an aircraft is detected.
