When you have a discrete random variable, each possible value in this variable can be assigned a positive probability. Why can't discrete random variables be assigned a positive probability to a possible value of this?
We know the properties of Discrete random variable,
A discrete random variable has a countable number of possible values.
The probability of each value of a discrete random variable is between 0 and 1, and the sum of all the probabilities is equal to 1. Probability is always lies between 0 to 1 hence it can always assigned positive probability to a possible value of above.
