1. Use your graph paper to plot a graph of the number of remaining dimes versus the number of throws (trial number).

2. What is the half-life of the dimes according to the graph? (The half-life will be indicated by the number of throws.)

3. Since the chance of a dime “decaying” is one in two, what is its theoretical half-life?

4. How does this graph simulate a decay graph of a radioactive substance?


5. On the same graph, use a different color and plot the number of remaining cubes versus the number of throws.


6. Staring with 50 cubes, redo the experiment, replacing cubes with spheres when the cube lands on 2 dots. Stop after 10 trials. Record and graph the results.


7. From the graph, what is the half-life of the cubes


8. How does this graph simulate the behavior of a radioactive daughter product?


9. On the same graph, use a third color to plot the number of spheres versus the

number of throws.


10. How does this graph simulate the behavior of a stable product
