STAT 206 Chapter 5: Discrete Probability Distributions 5.1 Probability Distribution for a Discrete Variable RECALL: discrete variables have numerical values that arise from a counting process ● Probability distribution for a discrete variable: mutually exclusive list of all the possible numerical outcomes along with the probability of occurrence of each outcome ● Expected value of a random variable is the mean (μ) of its probability distribution ○ Expec ted value > E(x) = ΣxᵢP(xᵢ) ■ Σ = the sum ■ Xᵢ = a possible outcome ■ P(xᵢ) = probability of that outcome ■ The sub ‘i’ represents whatever value you’re working with
