Understanding Probability Concepts

The video tutorial explains the concepts of probability and likelihood, highlighting their similarities and differences. It covers probability values, ranging from impossible (0) to certain (1), and uses examples like coin tosses to illustrate these concepts. The tutorial also discusses fair and biased scenarios, and demonstrates how to use tables and tree diagrams to solve probability problems, particularly with coin tosses.

What is the main difference between probability and likelihood?

• Probability is measured in words, likelihood in numbers.

• Probability is measured in numbers, likelihood in words.

• Probability and likelihood are both measured in numbers.
