Michaela’s class used a number cube that has sides labeled one through six. The students rolled the number cube 500 times and recorded the result for each roll. Which is the best prediction of the number of times the number cube landed on a side numbered greater than 4?
The number cube has 6 sides and 2 of them are greater than 4 (5 and 6). So, the probability of the cube landing on a side numbered greater than 4 is 2/6 or 1/3.
To estimate the number of times the cube landed on a side greater than 4, multiply the total number of rolls (500) by the probability (1/3):
500 * (1/3) = 166.67
Since you can't have a fraction of a roll, the best prediction is 167 times.
