SPINNING THE SPINNER

Go to the following link:
http://www.shodor.org/interactivate/activities/spinner3/index.html#
Now, follow the directions below:
Choose how many sections you
want on the spinner by clicking on +1 or -1. Choose 9 sections for this
round.
-
Leave "How Many Spins?" on 1. You
will be spinning 20 times, but do not change this because it spins all
20 at once and you can't watch the numbers change.
-
Calcualte the theoretical probability
BEFORE spinning. Show all of your work on a sheet of notebook paper.
-
Now, spin 20 times. Was your theoretical
probability correct? How close was it to the experimental?
-
Repeat this activity 5 times, showing
all of your work and responses.
