Standard 5.0 Knowledge of Probability: Students will use experimental methods or theoretical reasoning to determine probabilities to make predictions or solve problems about events whose outcomes involve random variation.
|
|
A. Sample Space
|
1. Identify a sample space
|
a. Describe the difference between independent and dependent events
|
b. Determine the number of outcomes
Assessment limit:
- Use no more than 5 dependent events with no more than 10 outcomes in the first event
|
|
B. Theoretical Probability
|
1. Determine the probability of an event comprised of no more than 2 independent events
|
a. Express the probability of an event as a fraction, a decimal, or a percent
|
2. Determine the probability of a second event that is dependent on a first event of equally likely outcomes
|
a. Express the probability as a fraction, a decimal, or a percent
Assessment limit:
- Use a sample space of no more than 60 outcomes
|
|
C. Experimental Probability
|
1. Analyze the results of a survey or simulation
|
a. Make predictions and express the probability of the results as a fraction, a decimal with no more than 2 decimal places, or a percent
Assessment limit:
- Use 20 to 500 results
|
2. Conduct a probability experiment
|
3. Compare outcomes of theoretical probability with the results of experimental probability
|
4. Describe the difference between theoretical and experimental probability
