Materials:
die
Analyze the Data
1. Find the theoretical probability of rolling a 2.
2. Find the theoretical probability of rolling a 1 or a 6.
3. Find the theoretical probability of rolling a value less than 4.
4. Compare the experimental and theoretical probabilities. Which pair of
probabilities was closer to each other: your individual probabilities or
your class’s probabilities?
Algebra 1—Chapter 14
5. Suppose each person rolls the die 50 times. Explain how this would
affect the experimental probabilities for the class.
Make a Conjecture
6. What can you conclude about the relationship between the number of
experiments in a simulation and the experimental probability?
