Essential Question: What is the real world probability of rolling certain outcomes with two dice?
Please Do Now:
Given two six sided dice, what is the probability of rolling the number 7 with the two dice? What is the probability of rolling 8? How do you know?
- In groups of either two or three students, roll a pair of dice 36 times and record the results on a sheet of paper.
- Create a three column spreadsheet within Microsoft Excel. Column 1 should contain the numbers 2 through 12. Column 2 should contain the theoretical probability of rolling each number when rolling the two dice 36 times. Column 3 should contain the actual results when rolling the two dice 36 times.
- Create a graph of your own choosing comparing the true mathematical probability with the actual results of the experiment.
- Answer the following questions: Are the results the same or different? If different, why are they different? How would you expect the results to change when rolling the dice 10 times? 100 times? 1000 times? Why?
