Exploring Sample Spaces in Probability

This video tutorial explains how to visualize outcomes from probability events using sample space diagrams. It covers different ways to present sample spaces, such as lists and tables, and demonstrates how to calculate probabilities using dice. The video also discusses the difference between theoretical and experimental probability, emphasizing how repeated trials bring experimental results closer to theoretical expectations.

What is a sample space in probability?

• A formula to calculate outcomes

• A specific outcome of an event

• A diagram showing probabilities

• All possible outcomes of an event

How can a sample space be represented?

• Using complex equations

• Only in a table

• As a list, table, or tree diagram

• Only as a list
