4.  Probability theory  Chance or likelihood of an event happening  Probability  Each even is assigned a number between 0 and 1.  Impossible Event – 0% chance  Certain Event – 100% chance

5.  Number of trials  Outcomes  Frequency  Relative frequency (fraction or percent)

6.  Example

9.  A sample space U is the set of all possible outcomes of an experiment. It is also referred to as the universal set U.  Ways to represent sample spaces: › Lists, tables of outcomes, 2D grids, Venn diagrams, tree diagrams.

10.  Mathematical or theoretical probability is based on what we theoretically expect to happen. Duh.

11.  In general, for an event A containing equally likely possible results, the probability of A occurring is  An ordinary 6-sided die is rolled once. Determine the chance of not getting a 1 or 2.

12.  Two events are complementary if exactly one of the events must occur. If A is an event, then A’ is the complementary event of A, or “not A”.
