Document Summary
5. 1 and 5. 2 chance experiments and probability concepts. These first two sections introduce basic terms and computational formulas. An experiment is an act or process of watching that leads to a single outcome that cannot be predicted with certainty. A simple event, or sample point, is the most basic outcome of an experiment, and the sample space is the collection of all its simple events. An event is a specific collection of simple events. Example: referring to the experiment in the previous example, define the event rolling an even number as event . Draw a venn diagram depicting the sample space and event . Example: consider as an experiment tossing a coin twice: draw a tree diagram depicting all possible outcomes. Draw a venn diagram depicting the sample space and event , the event that both tosses come up heads. The book identifies different methods of assigning probabilities to events. All methods must meet the two following criteria:
