Probability Tree Diagrams

Front

What is a probability tree diagram?

Back

A visual representation used to show all possible outcomes of a probability experiment, illustrating the paths leading to each outcome.

Front

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

Back

Multiply the number of outcomes at each stage of the experiment.

Front

If you roll a die (6 outcomes) and flip a coin (2 outcomes), how many total outcomes are there?

Back

12 outcomes (6 x 2 = 12).

Front

What is a sample space in probability?

Back

The set of all possible outcomes of a probability experiment.

Front

How do you represent combinations in a probability tree diagram?

Back

Each branch represents a choice, and the endpoints show the combinations of outcomes.

Front

If a cafeteria offers 3 types of sandwiches and 2 types of drinks, how many combinations can you make?

Back

6 combinations (3 sandwiches x 2 drinks = 6).

Front

What is the formula to find the number of variations when choosing from multiple options?

Back

Multiply the number of choices for each option.

Front

In a spinner with numbers 2, 4, 6 and another with 1, 3, 5, what is the sample space when spinning both?

Back

(1, 2), (1, 4), (1, 6), (3, 2), (3, 4), (3, 6), (5, 2), (5, 4), (5, 6).

Front

If you have 2 types of milk and 2 types of cookies, how many snack combinations can you create?

Back

4 combinations (2 milks x 2 cookies = 4).

Front

What does each branch in a probability tree diagram represent?

Back

Each branch represents a possible outcome or choice in the experiment.
