1. 8-3: Probability and Probability Distributions English Casbarro Unit 8

2. Probability and Odds An event that can never occur has a probability of 0. An event that will definitely occur has a probability of 1. All other probabilities are numbers between 0 and 1.

4. Definition of Odds  Odds are another way to show how likely an event is to be a success.  Probability has success: total (both success and failure)  Odds has success: failure (you would add them together to show the total number of events)

11. Probability Distribution (the total of all entries is 1) A probability distribution for a particular random variable is a function that maps the sample space to the probabilities of the outcomes in the sample space. A distribution where all of the probabilities are the same is called a uniform distribution.

13. Notice that all probability distributions add up to 1.

14. This is a frequency distribution of an experimental sample space that we can use to make a probability distribution.
