Geometric Probability (Links to Spinners)

Go back to: General discussion

Geometric probability can be explored with the spinners
shown above.  Questions such as, "How much more likely
is it you will land on color X than color y?" are often
used with any spinner.  Some spinners are well suited to
the question, "How likely is it you will land on color X
followed by Y and then Z?  But my favorite is, "Which
spinner is the most unfair one to use with a friend who
doesn't 'get it'?"

Using GeoGebra to make the six-degree tool is a challenge
you may want to try.
