Probability Final Review

Front

What is 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 the formula for calculating probability?

Back

The probability of an event is calculated as: P(Event) = (Number of favorable outcomes) / (Total number of outcomes).

Front

What does it mean if an event has a probability of 0?

Back

A probability of 0 means that the event cannot occur.

Front

What does it mean if an event has a probability of 1?

Back

A probability of 1 means that the event is certain to occur.

Front

What is an experimental probability?

Back

Experimental probability is the probability determined by conducting an experiment and observing the outcomes.

Front

How do you find the experimental probability of an event?

Back

Experimental probability is found using the formula: P(Event) = (Number of times the event occurs) / (Total number of trials).

Front

What is a spinner in probability?

Back

A spinner is a circular device divided into sections, each representing a different outcome, used to demonstrate probability.

Front

What is the difference between theoretical and experimental probability?

Back

Theoretical probability is based on expected outcomes, while experimental probability is based on actual outcomes from experiments.

Front

What is a sample space?

Back

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

Front

What is a favorable outcome?

Back

A favorable outcome is an outcome that satisfies the conditions of the event for which probability is being calculated.
