    Study Notes

    Probability Concepts

    • Probability: Measures the likelihood of an event occurring.
    • Sample Space: Represents the complete set of all possible outcomes for an experiment.
    • Theoretical Probability: Calculated as the ratio of favorable outcomes to total outcomes.

    Event Relationships

    • Complement of an Event: Refers to the probability that the event does not occur.
    • Independent Events: Outcomes of one event do not influence the outcomes of another.
    • Dependent Events: The outcome of one event affects another. Probability is given by P(A and B) = P(A) x P(B after A).

    Conditional Probability

    • Conditional Probability: Probability of one event occurring given that another event has already occurred.
    • Notation: Denoted as P(B/A), representing the probability of B given A.
    • Reading Conditional Probability: Understand it as the probability of B occurring given the occurrence of A.
    • Conditional Probability Formula: Expressed as P(B/A) = P(B and A)/P(A).

    Probability Calculations

    • AND Probability: For independent events, the joint probability is P(A and B) = P(A) x P(B).
    • OR Probability: For calculating the probability of either event occurring, use P(A or B) = P(A) + P(B) - P(A and B).
