Probability Concepts and Calculations

The video tutorial introduces the concept of probability, explaining it as a measure of how likely an event is to occur. It covers the basic probability values, such as 0% (impossible) and 100% (certain), and demonstrates how to calculate probability using examples with M&Ms, tiles, and dice. The tutorial also provides instructions for homework, emphasizing the importance of showing work and using resources for help.
