What is an event in probability?

Back

An event is a specific outcome or a set of outcomes from a probability experiment.

Front

What is a probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

What is a sample space?

Back

A sample space is the set of all possible outcomes of a probability experiment.

Front

What is an outcome in probability?

Back

An outcome is the result of a single trial of a probability experiment.

Front

What is an experiment in probability?

Back

An experiment is a procedure that produces outcomes, such as flipping a coin or rolling a die.

Front

What is the difference between an event and an outcome?

Back

An event is a collection of one or more outcomes, while an outcome is a single result of an experiment.

Front

How do you calculate the probability of an event?

Back

The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Front

What is a favorable outcome?

Back

A favorable outcome is an outcome that satisfies the conditions of the event we are interested in.

Front

What does it mean if an event is certain?

Back

If an event is certain, it has a probability of 1, meaning it will definitely occur.

Front

What does it mean if an event is impossible?

Back

If an event is impossible, it has a probability of 0, meaning it cannot occur.
