It is known that, mean is the average value of a set of observation.
Assume a set of random variables X for size N, as $$X_{1}, X_{2},.....X_{n}$$.
Now, the mean of the set of random variables is defined as,
$$M = \frac{\sum x}{n}$$ where M is he mean,sum X defines the sum of all random variables of size N and N is the size of the set of random variables.
