Use them and clarify your queries. To determine the probability of rolling any one of the numbers on the die, we divide the event frequency (1) by the size of the sample space (6), resulting in a probability of 1/6. In contrast to the probability of throwing a certain number by having n tries (either throwing n dice together or throwing a die n times), the probability of rolling the same face value on a number of dice decreases substantially the more dice there are. Rolling two fair dice more than doubles the difficulty of calculating probabilities. The total number of combinations for a pair of cube dice is 36.
