Ch. 7 Probability Review

Front

What is probability?

Back

Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1, or as a percentage.

Front

What is the sample space?

Back

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

Front

What is a tree diagram?

Back

A tree diagram is a visual representation that shows all possible outcomes of an event, branching out from a starting point.

Front

How do you calculate the total outcomes of two independent events?

Back

Multiply the number of outcomes of the first event by the number of outcomes of the second event.

Front

What is theoretical probability?

Back

Theoretical probability is the probability of an event occurring based on the possible outcomes in a perfect scenario.

Front

What is experimental probability?

Back

Experimental probability is the probability of an event occurring based on the results of an actual experiment.

Front

What does a probability of 0 mean?

Back

A probability of 0 means that the event is impossible and will not occur.

Front

What does a probability of 1 mean?

Back

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

Front

How do you express probability as a percentage?

Back

To express probability as a percentage, multiply the probability (a number between 0 and 1) by 100.

Front

What is the formula for calculating probability?

Back

Probability = (Number of favorable outcomes) / (Total number of possible outcomes).
