Use the spinner provided to answer the following questions. Complete a probability model. Outcomes Probability Is this uniform or non-uniform, explain your reasoning. If the spinner is spun 1000 times, how many times would you expect to have it land on green?

Outcomes Probability RED BLUE GREEN

Which spinner has the greatest chance of landing on red? Which, if any, of the spinners is uniform. Explain your reasoning.

Which spinner has the greatest chance of landing on red? Which, if any, of the spinners is uniform. Explain your reasoning. None of the spinners are uniform. They all have uneven spaces for each color.

A coin is tossed 27 times, and it lands on heads 15 times. How does the experimental probability of getting heads compare to theoretical probability, include the percent error?
