Key Concepts

Collectively Exhaustive

Events are said to be collectively exhaustive if their union covers the entire sample space. This means that one of the events must occur in every trial of the experiment, ensuring that all possible outcomes are accounted for.

Union

The union of two events is the set that includes all outcomes that are in either event or in both. This operation combines the outcomes from the individual events, and it is vital for understanding events that may occur in various scenarios.

Intersection

The intersection of two events refers to the set containing all outcomes that are common to both events. It is a fundamental set operation that helps in determining the overlap or shared outcomes, which is essential in computing joint probabilities.

Events

An event is any subset of the sample space. It represents a collection of outcomes that share a common property or satisfy a certain condition, forming the basis for probability calculations and set operations such as intersections and unions.

Sample Space

The sample space is the complete set of all possible outcomes in a probability experiment. It serves as the universal set within which all events are defined and analyzed, ensuring that probabilities are assigned over a well-defined set of outcomes.
