A probability distribution is a mathematical object that describes how likely different events are. In general, these events are restricted somehow to a set of possible events, such as for a die (we exclude undefined). A common and useful conceptualization in statistics is to think data is generated from some true probability distribution with unknown parameters. Then, inference is the process of finding out the values of those parameters using just a sample (also known as a dataset) from the true probability distribution. In general, we do not have access to the true probability distribution and thus we must resign ...
