This lesson involves investigating simulations used to observe long-run relative frequencies.

• Students will conduct simulations with multiple trials.
• Students will use relative frequencies to compute experimental probabilities.
• Students will informally explore the use of a simulation to observe long-run relative frequencies.

• Law of Large Numbers

This lesson involves investigating simulations used to observe long-run relative frequencies.
As a result, students will:

• Simulate drawing blue and red marbles one at a time from a bag.
• Generate a scatter plot of the relative frequencies of blue marbles.
• Examine variations in the scatter plots generated by the simulations.
• Determine and discuss any consistent patterns or trends found in the results of these simulations.
