    Study Notes

    Probability Distributions Overview

    • Conditional Distribution: Describes the likelihood of an event occurring given the outcome of another event, highlighting dependency.
    • Marginal Distribution: A function of one variable, focusing on the probabilities of individual events without considering others.
    • Independent Events: Likelihood of an event occurs is described by the Marginal Distribution, which operates independently of other variables.

    Other Key Distributions

    • Joint Probability Distribution: Can be used to calculate conditional distributions. It represents the probability of multiple events occurring simultaneously.
    • Conditional Distribution Variables: A function of two variables—the event given the condition of another event.

    Marginal vs Conditional Distribution

    • Marginal Distribution Characteristics: Some facts include that it sums or integrates the probabilities of a joint distribution across other variables.
    • Conditional Distribution Characteristics: It assesses probabilities with respect to specific conditions, thus changes with varying conditions or outcomes.

    Calculation Methods

    • Marginal Probability Calculation: Can be computed from a joint probability distribution by summing or integrating over the other variable(s).
    • Conditional Distribution Variables: Functions of two variables, reflecting the dependency on the conditioning event.
