Probability and odds: Probability is the measure of the chance of an event occuring. Thus, it is the likelihood of the event happening. If the desired outcome is achieved, it is considered a success. All other outcomes are considered failures. Odds are simply another way of writing the chances of an event occuring. Instead of having what is wanted over the total, it is what is wanted over what is not wanted. Odds and probability are most useful when considering sporting events, though they can be applied to other areas when it is desirable. It would not be smart to apply this to every aspect of life, but it has its uses. I. Chapter 9.7 (collin) a. Probability of an event (collin) i. 6 example problems (collin) ii.

Glossary of terms: Basic counting principle – the multiplication of each indepentent event Certain Event – an event that must occur Complement of an event – every number in a sample space that has not occurred in a specific event Experiment – a happening with an uncertain result Event – a sub-collection of a sample of an experiment Impossible event – An event that can not occur Independent – if, in two events, neither event effects the other Mutually exclusive – when two events share the same sample space but have none of the same results Outcomes – The results possible for an experiment Probability – Likelihood of an event occuring Sample space – Set of all possible outcomes of the experiment With replacement – an outcome is replaced after each experiment Without replacement – an outcome is not replaced after each experiment
