Example B
You are spinning a spinner like the one shown below 50 times. How many times does it land on blue? How about
if you spin it 100 times? Does the experimental probability get closer to the theoretical probability? Simulate the
spinning of the spinner using technology.
Set the spinner to spin 50 times and choose SPIN by pressing
WINDOW.
You can see the result of each trial by choosing TABL, or pressing
GRAPH.
Again, we can see the graph of the resulting table, or go back to the first screen, simply by choosing GRPH, or
pressing
GRAPHagain.
