Basic Concepts of Probability

A conditional probability is the probability that an event has occurred, taking into account additional information about the result of the experiment.
A conditional probability can always be computed using the formula in the definition. Sometimes it can be computed by discarding part of the sample space.
Two events $A$ and $B$ are independent if the probability $P(A \cap B)$ of their intersection $A \cap B$ is equal to the product $P(A) \cdot P(B)$ of their individual probabilities.
