The rule is useful in the study of Bayesian networks, which describe a **probability** distribution in terms of **conditional probabilities**.

.

We denote it P(A|B). .

For example, the **probability** of getting a six given that the number we have got is even: P(Six|Even) = 1/3.

. According to the **conditional probability** formula, │ P ( E i │ A) = P ( E i ∩ A) P ( A). .

Theorem: If A and B are two dependent events then the** probability** of occurrence of A given that B has already occurred and is denoted by P.

**Probability** has been defined in a varied manner by various schools of thought.

p ( x, y | z) = p ( x, y, z) p ( z) = p ( x | y, z) p ( y, z) p ( z) = p ( x | y, z) p ( y | z) On the first step we use the definition of **conditional** **probability**. The Goodman–Nguyen–Van Fraassen **conditional** event can be defined as: A B = ⋃ i ≥ 1 ( ⋂ j < i B ¯ j , A i B i ) {\displaystyle.

When A and B are independent, P (A and B) = P (A) * P (B); but when A and B are dependent, things get a little complicated, and the formula (also known as Bayes Rule) is P (A and B) = P (A | B) * P (B). It is mainly derived from **conditional** **probability** formula discussed in the previous post.

The** formula** provides the relationship between P (A|B) and P (B|A).

When A and B are independent, P (A and B) = P (A) * P (B); but when A and B are dependent, things get a little complicated, and the formula (also known as Bayes Rule) is P (A and B) = P (A | B) * P (B).

. We denote it P(A|B). .

. We denote it P(A|B). e. Thus, we can say that **probability** of either head or tail is 1/2. We denote it P(A|B). In such cases, the alternative way of calculating is as: P (B) = P (B|A) * P (A) + P (B|not A) * P (not A) This is the formulation of the Bayes theorem which shows an alternate.

May 22, 2023 · **Bayes’ theorem** describes the **probability** of occurrence of an event related to any **condition**.

( 1) Using the multiplication rule of **probability**, │ P ( E i ∩ A) = P ( E i). .

It is also considered for the case of **conditional probability**.

The **conditional probability** of an event A given that an event B has occurred is written: P ( A | B) and is calculated using: P ( A | B) = P ( A ∩ B) P ( B) as long as P ( B) > 0.
