When calculating a probability, we are comparing the number of favorable outcomes to the number of possible outcomes. To calculate the probability of obtaining a number not greater than 4 when rolling a number cube, we will use the Probability Formula.
P=Favorable Outcomes/Possible Outcomes
On the number cube there are 6 numbers. This is the number of possible outcomes.
1, 2, 3, 4, 5, 6
Furthermore, there are 4 numbers that are not greater than 4. This is the number of favorable outcomes.
1, 2, 3, 4, 5, 6
Now we have enough information to calculate P(Not greater than4).
