A probability mass function has the following properties: 1. All probabilities are positive in the support.For example, the probability that a dice lands between 1 and 6 is positive, while the probability of all other outcomes is equal to zero. 2. All outcomes have a probability between 0 and 1.For example, the … See more The two most common examples of probability mass functions in practice are for the Binomial distribution and the Poisson distribution. … See more We often visualize probability mass functions with bar charts.
