A

Jon spins the spinner below 20 times and gets the following results:

1. What is the theoretical probability of spinning each letter?

2. What is the experimental probability of spinning each letter?

3. According to the results, which section is closest to the theoretical probability?

B

A- 2/5 B- 2/5 C- 1/5

A- 7/20 B- 9/20 C- 4/20

Spinning a “C”

directions for the experimental activity
Directions for the Experimental Activity:
  • At each station you will perform the experiment on your own.
  • In the third column you will divide how many times you got that favorable outcome by the total trials.
  • In the fourth column you will change that decimal to a percent.
  • When you finish the chart, as a group answer questions 1 and 2.
  • Compare the theoretical probability to your experimental probability.
  • You will have 10 minutes at each station. (we will do three stations today.)
