CHAPTER 3: Random Variables and Probability Distributions
1=2 if 4 x < 6 5=6 if 6 x < 10 1 if x 10; nd the probability mass function. Solution: Continuous Probability Distribution: 3.3 A density curve is a curve that is always on or above the horizontal axis, and has area exactly 1 underneath it. A density curve describes the overall pattern of a distribution. The area under the curve and above any

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.
