Random Experiment

A random or statistical experiment is one in which

(i) All possible outcomes of the experiment are known in advance.

(ii) A performance of an experiment results in an outcome that is not known in advance.

(iii) The experiment can be repeated under identical conditions.

Random Variable:

A random variable is a quality resulting from a random experiment that, by chance, can assume different values.

→ A discrete random variable may assume either a finite number of values or an infinite sequence of values.

Example:

 1,2,3,...

→ A Continuous random Variable may assume any numerical value in an interval or collections of intervals.

Example:

 1.0,1.1,1.2,1.3,...
