The concept of Random Variables

Briefly, a numerical description of the outcome of a statistical experiment, this experiment can be any experiment you prefer. Here is the basic concept of Random Variables to be understood better which can be helpful if you want to know probability more fundamentally. Also It is good for those who are obsessed with SOTA deep learning models which are basically constructed above probability.

Random Variables

A random variable is a numerical quantity whose value is determined by the outcome of a probabilistic experiment (takes random values). For example the students in a school.

Okayyy!! what does it mean??

Let’s see how it is with an example:

Assume a sample space as a set of students with their names as labels (to make it easier, a b c d …):
