Definitions:

Random Variable

An attribute whose numerical values stem from the occurrence of a random event.

Probability

Probability is a measure of the likelihood that an event will occur, often expressed as a number between 0 and 1, where 1 indicates certainty.

Mutually Exclusive Event

Situations or events that cannot occur at the same time, meaning the occurrence of one event precludes the occurrence of the other.

Independent Event

An independent event is an event whose outcome is not influenced by the outcome of another event; in probability, this means that the occurrence of one event does not change the probability of another.
