    Study Notes

    Systematic Study of Uncertainty

    • Involves analyzing unpredictable outcomes and making informed decisions based on incomplete information.
    • Utilizes statistical methods to assess risks and uncertainties in various fields such as finance, science, and everyday life.

    Definition of Probability

    • A measure of the likelihood of an event occurring, expressed as a number between 0 (impossible) and 1 (certain).
    • Can be calculated using modeling approaches or empirical methods, including experiments and observational studies.

    Decision-Making Contexts

    • Decisions under uncertainty occur in various scenarios, such as investment choices, health diagnoses, and strategic planning.
    • Factors considered include potential outcomes, their associated probabilities, and how those outcomes affect overall goals.

    Relative Frequency in Probability

    • Refers to the ratio of the number of times an event occurs to the total number of trials or observations.
    • Serves as an empirical way to estimate probabilities, based on actual data collected from experiments.

    What Probability Quantifies

    • Represents the degree of belief or confidence in the occurrence of an event.
    • Enables individuals and organizations to navigate risks by estimating how often certain outcomes are expected to occur within a certain context.
