- Roll two standard number cubes 20 times. Record your results in the space provided here, and keep track of which number is rolled first.
- Use your results to complete the “percentage of your rolls” column in the table. ("Doubles" means that both numbers rolled are the same.)
event number of possible outcomes percentage of your rolls actual probability
first cube is 6 6 , 16.7% 4 and a 6 in either order doubles doubles and the first cube is a 6 doubles or the first cube is a 6 first cube is not a 6 doubles and the first cube is not a 6 not doubles - Compare the actual probabilities to the percentages from your group.
- Why is the actual probability different from the percentage of rolls you made for each event?
