Probability One of the most familiar uses of statistics is to determine the chance of some  occurrence. For instance, what are the chances that it will rain tomorrow or that the  Chicago Cubs will win a World Series? These kinds of probabilities, although  interesting, are not the variety under discussion here. Rather, we are examining the  probability in statistics that deals with classic theory and frequency theory—events that  can be repeated over and over again, independently, and under the same conditions. Coin tossing and card drawing are two such examples. A  fair coin  (one that is not

This kind of event forms the basis of your understanding of probability and enables you to find solutions to everyday problems that seem far removed from coin tossing or card drawing. Probability helps us describe our conclusions in a way that takes the uncertainty from random sampling into account....
