- 1Random variableA function that assigns exactly one value to each point in a sample space for an experiment
- 2Two types of random variables-Discrete Random Variables
-Continuous Random Variables - 3Discrete Random Variable-take precise values on the real line
-assumes countable values where consecutive values separated by a certain gap. - 4Continuous Random Variable-can assume any value contained in one or more intervals on a real number line
- 5Probability Distributions-links a random variable X with the probability that x assumes a discrete value or a range or values
- 6Representation of Probability Distributions-table, function or formula
- 7Note: Random variables can be discrete or continuousNote: Probability distributions can also be discrete or continuous
- 8Properties of a Discrete Probability Distribution1.) Pr(X=x)>0 (or = to 0)
