## What is Random:

Random refers to that which is relative or depends on chance, which cannot be predicted. It is a word that derives from Latin random, and means "game of chance", "chance", "luck".

Some synonyms that can be used with respect to the term random are: fortuitous, casual, risky, uncertain, random. In English, the translation that can be used for the word random is random.

It is worth mentioning that the term random is used to use in everything that is related to games of chance, hence its synonyms also indicate the fortuitous or uncertain.

For example, in card games the distribution of cards is random and therefore it is uncertain for each player how well or badly the game can go.

What is random is not safe because it does not have an order and depends on luck, therefore, it is unpredictable and can lead to risk.

For example, "The exam will have random questions about everything studied in the semester", "The work groups will be formed randomly".

Now, since random events cannot be determined in advance, then, they are analyzed through science using statistics or probability theory in order to obtain a possible result. Random facts are also studied by philosophy.

## Simple random

Simple random or simple random sampling is called the technique in which all the elements that are part of a universe have the same probability of being selected as a sample.

However, the elements of the universe can be selected more than once in the sample, in those cases we speak of a simple random sample with replacement or without replacement.

If resetting is used, an item can be selected more than once. Otherwise, the item can only be selected once for the sample.

The most common example can be the drawing of numbers that is introduced into an urn and they are drawn randomly and the winning numbers are announced.

## Random experiment

Randomized experiments are those that contain a set of initial conditions, the possible results can be known, however, they cannot be predicted or be certain of what will happen.

For example, when you roll a die you know that any number between 1 and 6 can roll, but when you roll it you don't know which number will roll. These experiments are studied through probability theory.
