Discrete Random Variable &Nbsp;Is A Variable That Can Only Take On Discrete Values.
Where variable x consists of all possible values and p consist of respective probabilities. There is an easier form of this formula we can use. This calculator can help you to calculate basic discrete random variable metrics:
We Can Use The Probability Distribution Of A Random Variable To Calculate Its Mean (Or Expected Value) As Follows;
