In general, the marginal probability distribution of X can be determined from the joint probability distribution of X and other random variables. For example, to determine P(X = x), we sum P(X = x, Y = y) over all points in the range of (X, Y ) for which X = x. Subscripts on the probability mass functions distinguish between the random variables.51 Two Discrete Random VariablesExample 5251 Two Discrete Random VariablesFigure 52Marginal probability distributions of X and Y from Figure 51.51 Two Discrete Random VariablesDefinition: Marginal Probability Mass Functions51 Two Discrete Random Variables51.3 Conditional Probability Distributions51 Two Discrete Random Variables51.3 Conditional Probability Distributions51 Two Discrete Random VariablesDefinition: Conditional Mean and Variance...
