Sample SpaceIt is the set of all possible results of a random experiment. Each possible result in a random experiment is a sample point. Addition operations, multiplication (division) operations, and average operations can be performed in the sample space.

If you toss a coin, then the sample space is the set {heads, tails}; if you roll a dice, then the sample space is {1,2,3,4,5,6}.

Related definitions

• Sample space: The subset of all possible results of the experiment, that is, the sample space of the experiment. This definition indicates that the probability of the sample space is 1;
• Event: Any subset of the sample space is called an event;
• Set operations: Because events are sets, various set operations are required in probability calculations, including mutual complementation, commutative law, associative law, distributive law and De Morgan's laws.

Mutually exclusive events

Assume that there are two events E and F that are mutually exclusive (incompatible), then E ∩ F = ∅, that is, the two events cannot occur at the same time.
