Chapter 5: Discrete Probability Distributions
coconino.eduChapter 5: Discrete Probability Distributions 158 This is a probability distribution since you have the x value and the probabilities that go with it, all of the probabilities are between zero and one, and the sum of all of the probabilities is one. You can give a probability distribution in table form (as in table #5.1.1) or as a graph.
