If the spinner only has red, white, and blue regions, then what is
? Explain how you know.
What must the probabilities add up to?
What are the central angles of this spinner if it has only three sections? Draw a sketch of the spinner. Be sure to label the regions accurately.
Convert the probability from a percent to a decimal and multiply that by
to get the central angle.
; white ; blue
Is there a different spinner that has the same probabilities? If so, sketch another spinner that has the same probabilities. If not, explain why there is no other spinner with the same probabilities.
Think about a spinner with more than three regions but still only red, white, and blue.
