Chapter 5. Discrete Probability Distributions in the textbook: 5.1 The Probability Distribution for a Discrete Variable (pp. 186-188) It may be a good idea to work on your own to calculate the mean, ...

A discrete distribution is a probability distribution that depicts the occurrence of discrete (individually countable) outcomes, such as 1, 2, 3, yes, no, true, or false.

Discrete uniform distribution shows that variables in a range have the same probability of occurring. There are no variations in probable outcomes, and the data is discrete, rather than continuous.
