📚 In this lesson, you will learn:

How to understand the significance of conditional probability through real-life scenarios.

The formal notation for expressing conditional probability, denoted as P(A|B), meaning the probability of event A occurring given that event B has occurred.

The core formula for conditional probability: P(A|B) = P(A and B) / P(B).

The multiplication rule to calculate joint probabilities: P(A and B) = P(A|B) × P(B).

How to recognise and work with independent events, where the occurrence of one event does not affect the other.

An introduction to Bayes’ Theorem and its applications, such as updating probabilities based on new information.

✨ Key concepts covered:

Conditional Probability Notation: Master the use of specific notation to express relationships between events.

Core Formula and Applications: Learn how to calculate conditional probabilities and apply this knowledge to solve practical problems.

Multiplication Rule: Understand how to derive and use the multiplication rule for joint probabilities.

Independence of Events: Differentiate between dependent and independent events with an intuitive understanding of probability.
