Counting Principles and Sample Spaces

The video tutorial covers the counting principle and sample spaces, focusing on compound events and probability. It explains how to use tree diagrams and ordered pairs to find sample spaces, with examples involving coin flips and ice cream combinations. The counting principle is applied to calculate possibilities and probabilities, including a detailed example with dice. The tutorial concludes with a homework assignment and encourages students to bring questions to class.
