    Study Notes

    Probability

    Simple Events

    • A simple event involves a single occurrence or trial, where the probability can be calculated straightforwardly.
    • The probability of a simple event is calculated using the formula: P(event) = number of ways an event can happen / total number of possible outcomes.
    • Probability values can be expressed in three formats: fraction, decimal, and percentage.

    Compound Events

    • A compound event involves more than one occurrence or trial, where the probability calculation takes into account multiple possible outcomes.
    • Tree diagrams are visual tools used to map out all possible outcomes of events, with each branch representing different possible outcomes.
    • Two-way tables are used to compare two different variables, allowing for the determination of probability values and making predictions.

    Probability in Predictions

    • Historical trends are used to determine probability values, which are then used to predict future events.
    • Advertisements, such as car insurance rates, use historical data to predict the likelihood of accidents for different demographics.
    • Probability values predict the likelihood of events, but do not guarantee outcomes.

    Summary of Key Points

    • Simple events involve straightforward probability calculations and are expressed in three formats.
    • Compound events involve more complex calculations using tree diagrams and two-way tables.
    • Understanding the distinction between simple and compound events is crucial for accurately determining and interpreting probability values.
