Conditional Probability

Description:

Conditional Probability refers to the probability of an event occurring given that another event has already occurred.

Senses:

1. Mathematics:

   In mathematics, conditional probability is a measure of the probability of an event occurring, given that another event has already occurred. It is denoted by P(A|B) and is calculated using the formula P(A|B) = P(A ∩ B) / P(B).

   Example: The conditional probability of rolling a 6 on a fair six-sided die, given that the previous roll was an odd number, is 1/3.

Usages:

• Statistical Analysis: Conditional probability plays a crucial role in statistical analysis, allowing us to calculate and analyze the likelihood of events given certain conditions.
• Machine Learning: Conditional probability is widely used in machine learning algorithms for tasks such as classification, prediction, and recommendation systems.
