What is Random Variable?

Corresponding to every outcome of any random experiment, a real number is associated this correspondence between the elements of the sample space associated to a random experiment and the set of real numbers is defined as a random variable.

Example: Consider a random experiment of tossing 3 coins there are total of 8 possible outcomes i.e. TTT, TTH, THT, HTT, THH, HTH, HHT and HHH.

Therefore, the sample space S = { TTT, TTH, THT, HTT, THH, HTH, HHT, HHH }.

If Y is a random variable and p and q are real numbers, then Random Variable = pY + q, Mean = pY + q and variance = p.p Var (Y)
