From OECD Glossary of Statistical Terms:
Population is the total membership or population or “universe” of a defined class of people, objects or events.
From Wikipedia:
The posterior probability of a random event or an uncertain proposition is the conditional probability that is assigned after the relevant evidence is taken into account.
From (Wikipedia):
The powerset of the set S, P(S) or 2S, is the set of all subsets of S.
Adapted from Wikipedia:
In statistics, a sample is a subset of a population. Typically, the population is very large, making a complete enumeration of all the values in the population impractical...
