Algebra II Journal: Reflection 4

Respond to the following activities in your Algebra II Journal opens in new window and submit to your teacher.

Use this interactive version of the spinner to conduct a simulation to determine the probability that at least one game will be rained out in a three-game stretch.

Check Your Understanding

A copy of the table below appears in your Algebra II Journal. Use this table to record the outcomes of your simulation. Next, answer the following questions.


Number of


Number of










































  • How many three-day stretches, out of twenty stretches (i.e., trials), resulted in at least one game being a rain-out?
  • How many stretches were complete rain-outs (all three games were rained out)? Write your answer as a percent.
  • In your simulation, you simulated a total of 60 games (20 three-game stretches). What percentage of the sixty games resulted in a rain-out? Write your answer as a percent.
  • How close was your answer in the previous bullet to the population mean of 20%?
