Final answer:
The sample space is the collection of all possible outcomes of a chance experiment.
Step-by-step explanation:
The subject of this question is Mathematics and the grade level is High School.
The term being defined in this question is sample space. In probability theory, the sample space is the collection of all possible outcomes of a chance experiment. It is a set that contains all the possible results or outcomes of the experiment.
For example, if you toss a fair coin, the sample space would be {H, T}, where H represents heads and T represents tails. If you roll a fair six-sided die, the sample space would be {1, 2, 3, 4, 5, 6}. The sample space can be represented using a set notation, denoted by an uppercase S.
