equally likely

• the probabilities of all the outcomes of an experiment are equal.

• the outcomes of an experiment are independent of each other.

• the outcomes of an experiment are mutually exclusive.

• the probabilities of some outcomes are greater than others.

outcome

• the result of a single trial of a probability experiment

• the overall result of multiple trials

• a prediction made before an experiment

• the average of all trials conducted

non-uniform probability model

• when all probabilities in a probability model are equal to each other.

• when some probabilities in a probability model are greater than others.

• when all probabilities in a probability model are not equal to each other.

• when probabilities are assigned randomly in a probability model.

uniform probability model

• occurs when all probabilities in a probability model are all equally likely to occur

• occurs when some probabilities are more likely than others

• is a model that predicts outcomes based on historical data

• is a model that only applies to continuous random variables

event

• one possible outcome or a group of possible outcomes for a given situation.

• a planned public or social occasion.

• a significant occurrence that is noteworthy.

• a series of actions or steps taken to achieve a particular end.

outcome

• a list of all the possible outcomes.

• a summary of the main points discussed.

• a prediction of future events.

• a detailed analysis of past events.

experiment

• a situation involving chance that leads to results, or outcomes.

• a method of gathering data through observation and analysis.

• a process of making predictions based on previous knowledge.

• a technique used to manipulate variables in a controlled environment.

simple event

• an event consisting of one outcome.

• an event with multiple outcomes.

• an event that cannot occur.

• an event that is always certain.

theoretical probability

• the ratio of the number of desired outcomes to the total number of possible outcomes.

• the likelihood of an event occurring based on past occurrences.

• the chance of an event happening in a specific situation.

• the probability calculated using experimental data.

experimental probability

• the ratio of the number of times an event occurs to the total number of trials performed.

• the likelihood of an event occurring based on theoretical calculations.

• the percentage of successful outcomes in a given situation.

• the total number of events divided by the number of favorable outcomes.
