Unit 7 Basic Probability Terms

probability

• a number between 0 and 1 that expresses the likelihood of an event occurring

• a measure of the total number of outcomes in an event

• a value that can only be negative

• the certainty that an event will not happen

What is an outcome

• one of the possible results of a chance experiment

• a predetermined result of an experiment

• the initial conditions of an experiment

• a method to analyze data

tree diagram

• a visual that shows all possible outcomes of an experiment

• a type of graph used to represent data

• a method for calculating probabilities

• a diagram that illustrates a hierarchical structure

What is an event in probability?

• A single outcome of an experiment.

• The set of one or more outcomes of an experiment.

• A random number generated by a computer.

• The likelihood of an outcome occurring.

compound event

• an event that consists of two or more simple events

• a single occurrence that cannot be broken down

• an event that happens only once

• a random occurrence with no specific outcome

experiment

• a repeatable procedure involving chance that results in one or more possible outcomes

• a fixed method to achieve a specific result

• a random event with no predictable outcome

• a theoretical concept without practical application

sample space

• the set of all possible unique outcomes from an experiment

• a collection of all possible experiments

• the average outcome of an experiment

• the most likely outcome of an experiment

What is experimental probability

• the probability of an event occurring based on the results from an experiment.

• the likelihood of an event based on theoretical calculations.

• the chance of an event happening in the future without any data.

• the probability determined by historical data alone.

theoretical probability

• the probability of an event occurring based on what is expected to happen

• the probability of an event occurring based on past occurrences

• the probability of an event occurring based on random chance

• the probability of an event occurring based on subjective judgment

simulation

• an experiment designed to imitate or reproduce something in order to study it

• a method of data collection in research

• a type of statistical analysis

• a process of creating a model for prediction
