If you roll a dice 100 times how many times would you roll a three?
100/6 = 16.6 times
What is the mathematical probability for each number on a dice if you roll the dice fifty times?
If the dice is 6 sided, the chances of rolling each number is about 17% (100/6) If the dice is 4 sided, the chances of rolling each number is 25% (100/4) Similarly, 8 sided = 12.5% 10 sided = 10% 12 sided ≈ 8% 20 sided = 5%
What are the chances of rolling less than 20 on a pair of dice?
With 2 6-sided dice, 100% chance, since the maximum roll is 12.
What if 2 dice are rolled 100 times what is the probability that it will be a prime number?
There are 36 permutations of two standard 6 sided dice. Of those, 15 are prime, namely 2, 3, 3, 5, 5, 5, 5, 7, 7, 7, 7, 7, 7, 11, and 11. The probability of rolling a prime number, then, is 15 in 36, or 5 in 12, or about 0.4167. It does not matter how many times you roll the dice.
What is probability of rolling doubles with 2 dice 100 times?
The probability of rolling doubles with 2 dice is 1 in 6, or about 0.1667. The probability of doing that 100 times in a row is 0.1667100 or about 1.531x10-78.
