Making Predictions and Carrying Out Probability Experiments

Today students carried out a probability experiment. Below is the action task. Students rolled a number cube 20 times to find out how many times 1 and 2 are rolled compared to 5 and 6 (if they got a 4 then they rolled again). We pooled all of our results and discover that out of 183 rolls, less than 4 (1,2,3) was rolled 107 times where as greater than 4 (5,6) was rolled 76 times. This confirmed students' predictions that less than 4 would be rolled more often than more than 4.
