Instructions
Play through this interactive game to learn about Approximate Probability. Suitable for Grade 6, Grade 7, Grade 8.
Main Concepts
If the number of outcomes are unknown then the approximate frequency can be found by making a series of random selections and recoding the relative frequencies.
Make a prediction with probability.
A probability model provides a probability for each possible nonoverlapping outcome for a chance process so that the total probability over all such outcomes is unity.
Probabilities can be theoretical (based on the structure of the process and its outcomes) or empirical (based on observed data generated by the process).
Theoretical probabilities are expressed as equal in likelihood based on the process of gathering the data being random and balanced.
Develop a theoretical probability model that gives equally likely outcomes for success.
If the outcomes are unknown for a probability model you can approximate it by making a series of random selections and recording the relative frequencies in a table or tree diagram.
Data gathered and displayed from unknown structures is known as statistics versus probability from known structures.
Determine the probability of an event based on the relative frequency.
Discussion Questions
Before the Game
What is a fraction? How do you convert fractions into decimals? What does it mean to say these dice are fair (show a pair of dice)? How would you know that a pair of dice are not fair?
After the Game
How did you decide which two dice to choose in order to reach the target sum? Looking at the probability model of each die, why would you suspect these were not fair dice (even if the game did not tell you)? Does the probability model of a die guarantee that the die is unfair?
