The video tutorial introduces probability models, explaining their purpose and how to create them. It uses examples like a spinner and exercises involving candies and balloons to demonstrate calculating probabilities. The tutorial emphasizes comparing outcomes using different probability formats, such as fractions, decimals, and percentages.

What is the primary objective of using a probability model in this lesson?

• To list all possible outcomes of an event

• To create a mathematical description of an event

• To find the probability of an event

• To compare different probable outcomes

Which of the following is NOT a way to express probabilities in a probability model?

• As a fraction

• As a decimal

• As a percentage

• As a ratio
