Key Concepts

Complement of an Event

The complement of an event includes all outcomes in the sample space that are not part of the event. It represents the scenario that the event does not occur, thus covering every possibility that was excluded from the original event.

Complement Rule

The complement rule in probability states that the probability of the complement of an event is equal to one minus the probability of the event itself (i.e., P(Event') = 1 - P(Event)). This rule is fundamental for calculating the probability of an event not happening when the event's probability is known.

Probability

Probability is a measure of the likelihood that a particular event will occur. It is expressed as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty, thus ensuring that the total probability across all mutually exclusive outcomes in the sample space sums to 1.
