Notes 7-1

The document discusses probability theory and concepts like sample space, outcomes, events, and the probability of events occurring. It provides examples of calculating probabilities, including rolling dice. The key points are: - Probability theory is the study of chance using mathematics - An experiment is a situation with possible results called outcomes - The sample space includes all possible outcomes - An event is a subset of outcomes of interest within the sample space - Probability is calculated as the number of favorable outcomes divided by the total number of possible outcomes - Examples are provided to demonstrate calculating probabilities, such as the probability of rolling a 7 when rolling two fair dice.
