Study Notes

Probability and Statistics: Chapter 7

  • Possible Outcomes: Determining the various results possible in a scenario.

Probability of an Event

  • Example Problem: A cube numbered 1 to 9. What's the probability of rolling an odd number?
    • There are 5 odd numbers (1, 3, 5, 7, 9) out of 9 total possible outcomes.
    • The probability is 5/9.

Finding Possible Outcomes: Two Events

  • Method: Using a table or tree diagram to visualize all possible outcomes when performing two or more events.
  • Example: Spinning a spinner twice.
    • Outcomes are listed systematically (e.g., spin 1 = heads, spin 2 = heads).
  • Total Outcomes: The total number of possible outcomes of the combined events is determined.

Probability of Specific Outcomes

  • Calculation: Finding the probability of a particular combination of outcomes in a series of events.
    • Determine all possible outcomes.
    • Identify the desired outcome(s).
    • Calculate the fraction: (Number of desired outcomes) / (Total number of possible outcomes).

Coin and Spinner Experiment (Example)

  • Method: A tree diagram reveals all potential results when flipping a coin and spinning a spinner.
    • The diagram branches out to show outcomes combining coin flips with spinner results.
  • Total Outcomes: The count of unique results is calculated.

Determining Possible Outcomes: Multiple Experiments (Example)

  • Diagram: A tree diagram clearly illustrates all possible outcomes of flipping three coins.
  • Count: The diagram provides a visual method for counting the total number of possible outcomes

Identifying Errors in Probability Calculations

  • Example: Calculating the probability of getting heads twice in a row when flipping a coin.
    • One student might miscalculate.
    • Another student correctly determines two heads as one outcome from the possible four outcomes, making the probability 1/4.
