This video tutorial explains how to use sample space diagrams to calculate probabilities. It covers two examples: rolling two four-sided dice and spinning a three-sided spinner with a coin flip. The video demonstrates how to list all possible outcomes and calculate probabilities for specific events, such as rolling a total score of six or more. The tutorial concludes with a call to subscribe for more math tutorials.

What is a sample space diagram used for?

• To eliminate impossible outcomes

• To determine the fastest outcome

• To calculate the average of outcomes

• To list all possible outcomes of an event
