To solve this problem, let us first define probability. We know in statistics class that probability is simply the ratio of a selected event to occur over the total number of events. That is:
probability = number of selected event to occur / total number of events
In this scenario, our only selected event to occur is to have a dice roll of 4. That is 1 event only. Now since there are 6 number in the dice, therefore the total number of events is 6. Therefore:
probability = 1 / 6
probability = 0.1666667
Rounding off to the nearest hundredth:
probability = 0.17
