Define the term 'outcome' in probability.
An outcome is a collection of all possible results of a random experiment.
An outcome is the probability of an event occurring.

Explain what a 'sample space' is in probability.
The sample space is a single outcome from a random experiment.
The sample space is the set of all possible outcomes of a random experiment.
The sample space is the most likely outcome of an experiment.
The sample space is the average of all outcomes.

What does it mean if two events are 'independent' in probability?
Two events are independent if they always occur together.
Two events are independent if one event guarantees the occurrence of the other.
Two events are independent if the occurrence of one does not affect the other.
Two events are independent if they are both impossible to happen.

Explain the difference between 'theoretical probability' and 'experimental probability'.
Experimental probability is calculated using expected outcomes, while theoretical probability is based on actual trials.
Theoretical probability is calculated using expected outcomes, while experimental probability is based on actual trials.
Theoretical probability is always accurate, while experimental probability is never reliable.
Theoretical probability is only used in games of chance, while experimental probability applies to all situations.
