Conditional Probability
Video lessons with examples and solutions to help High School students to
understand the conditional probability of A given B as
P(A and B)/P(B), and interpret
independence of A and B as saying that the conditional probability
of A given B is the same as the probability of A, and the
conditional probability of B given A is the same as the probability
of B.
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.

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.
