OUTLINE of Chapter 4 text - Elementary Statistics: A Brief Version (A. Bluman 3rd Ed., 2003)

Chapter 4 Outline Determine sample spaces and find the probability of an event using classical probability or empirical probability. Find the probability of compound events using the addition rules. Find the probability of compound events using the multiplication rules. Find the conditional probability of an event. Determine the number of outcomes of a sequence of events using a tree diagram. Find the total number of outcomes in a sequence of events using the fundamental counting rule. …

…occurring. It can be used to quantify what the "odds" are that a specific event will occur. Some examples of how probability is used everyday would be weather forecasting, "75% chance of snow" or for setting insurance rates. Conclusions A tree diagram can be used when a list of all possible outcomes is necessary. When only the total number of outcomes is needed, the multiplication rule, the permutation rule, and the combination rule can be used.
