Description:

Conditional ProbabilityWhen dealing with two events (usually called A and B), sometimes the events are so related to each other, that the probability of one depends on whether the other event has occurred. When we talk about probabilities based on the fact that something else has already happened we call this conditional probability.A tutorial with interactive exercises from algebralab.org

Conditional Probability
When dealing with two events (usually called A and B), sometimes the events are so related to each other, that the probability of one depends on whether the other event has occurred. When we talk about probabilities based on the fact that something else has already happened we call this conditional probability.
