Bayes' theorem is named after Reverend Thomas Bayes, who worked on conditional probability in the eighteenth century. Bayes' rule calculates what can be called the posterior probability of an event, taking into account prior probability of related events . In probability theory and applications, Bayes' theorem shows the relation between a conditional probability and its reverse form. For example, the probability of a hypothesis given some observed pieces of evidence, and the probability of that evidence given the hypothesis. This theorem is named after Thomas Bayes (/ˈbeɪz/ or "bays") and is often called Bayes' law or Bayes' rule. Bayes’s theorem is written, in mathematical notation, as P(A|B) = (P(B|A)P(A))/P(B).

Our tests and measuring equipment have a rate of error to be accounted for. Bayes’ theorem converts the results from your test into the real probability of the event.

So, Bayes' Rule represents the probability of an event based on the prior knowledge of the conditions that might Bayes' theorem captures how the probability of a white object changed from the prior probability of P(W)=＿ to the posterior probability of P(W|S)=＿ that is based Conditional Probability, Independence and Bayes' Theorem.
In finance, Bayes' theorem can be used to rate the risk of lending
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. 2020-09-25
Bayes' theorem is to recognize that we are dealing with sequential events, whereby new additional information is obtained for a subsequent event, and that new information is used to revise the probability of the initial event.

We advocate teaching Conditions are given which suffice for the assessment of a coherent inference by means of a Bayesian algorithm, i.e., a suitable extension of the classical Bayes differences between discrete and continuous probability theory, the primary difference in the equations for Bayes' Theorem with discrete or continuous random Bayes' theorem (also known as Bayes' rule or Bayes' law) is a result in probabil- ity theory that relates conditional probabilities. If A and B denote two events,.
An important application of Bayes’ theorem is that it gives a rule how to update or revise the strengths of evidence-based beliefs in light of new evidence a posteriori. As a formal theorem, Bayes’ theorem is valid in all interpretations of prob-ability. Bayes' theorem is a formula that describes how to update the probabilities of hypotheses when given evidence.

In other words – it describes the act of learning. The equation itself is not too complex: Bayes' theorem is a mathematical equation used in probability and statistics to calculate conditional probability. In other words, it is used to calculate the probability of an event based on its association with another event. The theorem is also known as Bayes' law or Bayes' rule.
