In Chapter 4, you learned to use the rules of probability to make inferences concerning a particular outcome. In practice, the probability of many events is unknown, so probability models are developed to estimate the probabilities of occurrence for different values.

Probability Distributions for Discrete Variables

Probability distributions for a random variable summarize or model the probabilities associated with the events for that random variable. Such distributions ...
