Introduction to Probability


This chapter explains the differences between probabilistic statistics and descriptive statistics, showing in which situations the probability theory must be used. The concepts and terminologies related to probabilistic statistics are presented here, as well as their practical application. By using the probability theory, it is possible to predict the occurrence of one or more events. This chapter also shows how combinatorial analysis can be used to calculate probabilities.
