4. 2: Probability Distributions for Discrete Random Variables The probability distribution of a discrete random variable X X is a listing of each possible value x x taken by X X along with the probability P(x) P (x) that X X takes that value in one trial of the experiment
Consider the given the probability distribution x 0 1 2 3 4 5 px To calculate the variance of a probability distribution, you can use the formula: Variance (σ^2) = Σ [ (x - μ)^2 * p (x) ] Where: First, calculate the mean (μ) of the distribution: μ = Σ [ x * p (x) ] μ = (0 0 001) + (1 0 031) + (2 0 24) + (3 0 41) + (4 0 4) + (5 0 151) μ = 2 15
Consider the given the probability distribution x 0 1 2 3 4 5 p (x) 0. . . .
