Conditional Probability

Lessons here cover:

• Understand conditional probability and how it applies to real-life events.
• Use p(A|B) = p(A ∩ B)/p(B) to calculate conditional probabilities.
• Understand that events A and B are independent if and only if they satisfy p(A|B) = p(A) or satisfy p(B|A) = p(B).
• Apply the definition of independence to a variety of chance events.

Conditional Probability
This video explains how to determine conditional probability.

How to Calculate Conditional Probability
Tutorial on how to calculate conditional probability for two events P(A), P(B), P(B|A) with two examples.

Conditional Probability: Basic Definition
This is a sample video from my tutorial course on the Rules for Reasoning with Probabilities. In this video I introduce the basic definition of conditional probability as it's defined in standard probability theory.



Basic Conditional Probability Example
This video looks at a basic conditional probability example. Conditional probability is simply calculating a probability on the 'condition' that something already happened. In this case, the condition we assume is that John already selected a science card when selecting the next card.
