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.
