Is the table considered a discrete probability distribution?
Thus, the table is an example of a probability distribution for a discrete random variable.
How will you identify the properties of probability distribution for a discrete random variable?
A discrete probability distribution function has two characteristics: Each probability is between zero and one, inclusive. The sum of the probabilities is one. The expected value is often referred to as the "long-term" average or mean.
