Probability Tree Diagrams

Front

What is a probability tree diagram?

Back

A visual representation that shows all possible outcomes of a probability experiment, illustrating how outcomes branch out from each event.

Front

How do you calculate the total number of outcomes in a probability tree diagram?

Back

Multiply the number of outcomes for each event together. For example, rolling a die (6 outcomes) and flipping a coin (2 outcomes) gives 6 x 2 = 12 total outcomes.

Front

What is a sample space?

Back

The set of all possible outcomes of a probability experiment.

Front

What does each branch in a probability tree diagram represent?

Back

Front

If you flip two coins, what is the sample space?

Back
