Assume we want to determine the probability of rolling a 2 or smaller of a fair die (If it isn't, then some probabilities of getting a certain number must be different from the usual).
List the possibilities for such event. We have:
P(2 or smaller) = P(2) + P(1)
The probability of obtain a number on a die is 1/6. Therefore, the probability of obtaining a 2 or smaller on a fair die is 1/6 + 1/6 = 2/6 = 1/3.

What is the probability of rolling a 2 on a die and then re-rolling the die and getting an even number?
The probability of rolling a 2 is 1 in 6. The probability of rolling an even number is 3 in 6. The probability of doing both, on two rolls, is 3 in 36, or 1 in 12.
What is the probability of flipping a coin and getting tails and than rolling a number greater than two on a number cube?
The probability of getting tails on a coin is SMALLER than rolling a number greater than 2
What is the probabilities of rolling a 2 with two dice?
The probability of rolling a sum of 2 is 1/36 The probability of rolling the value 2 on one die or the other (or both) is 11/36
If you roll two fair dice what is the probability a three or six will appear?
Probability of rolling a 3 is 2/36 & the probability of rolling a 6 is 5/36; probability of rolling a 3 or 5 is 2/36 + 5/36 = 7/36.
How do you get the probability of three dice rolls?
The probability of 3 specific dice rolls is the probability that each one will happen multiplied together. For instance, the probability of rolling 2 then 6 then 4 is the probability of all of these multiplied together: The probability of rolling 2 is 1/6. The probability of rolling 6 is 1/6. The probability of rolling 4 is 1/6. Multiply these together and we get the total probability as 1/216
What is the probability of rolling a ten or more when rolling 2 dice?
The probability is 1/6.
What is the probability of rolling a 7 or 11 with two dice?
The probability of rolling a 7 with 2 dice is 6/36; probability of rolling an 11 is 2/36. Add the two together to find probability of rolling a 7 or 11 which is 8/36 or 2/9.
What is the probability of rolling a 2 on a die and then re-rolling the die and getting an even number?
The probability of rolling a 2 is 1 in 6. The probability of rolling an even number is 3 in 6. The probability of doing both, on two rolls, is 3 in 36, or 1 in 12.
When rolling one die 12 times what is the probability of rolling a 2?
The probability of rolling at least one 2 when rolling a die 12 times is about 0.8878. Simply raise the probability of not rolling a 2 (5 in 6, or about 0.8333) to the 12th power, getting about 0.1122, and subtract from 1.
What is the probability of flipping a coin and getting tails and than rolling a number greater than two on a number cube?
The probability of getting tails on a coin is SMALLER than rolling a number greater than 2
What is the probabilities of rolling a 2 with two dice?
The probability of rolling a sum of 2 is 1/36 The probability of rolling the value 2 on one die or the other (or both) is 11/36
If you roll two fair dice what is the probability a three or six will appear?
Probability of rolling a 3 is 2/36 & the probability of rolling a 6 is 5/36; probability of rolling a 3 or 5 is 2/36 + 5/36 = 7/36.

What is the probability of rolling a 3 or 5 on a die?
a 2 out of 6 probability
What is the probability of rolling a sum of 11 with 2 dice?
The probability of rolling a sum of 11 with 2 dice is: P(11) = 1/18.For explanation see answer to question: "What is the probability of rolling 7 or 11 with 2 dice?".Read more: What_is_the_probability_of_rolling_7_or_11_with_2_dice
If you alternate between flipping a coin and rolling a die what is the probability of rolling a 2 before flipping a heads?
The probability of rolling a 2 on a die before flipping a heads on a coin is 1 in 12. The probability of rolling a 2 is 1 in 6. The probability of flipping heads is 1 in 2. Since these are sequentially unrelated events, you simply multiply the probabilities together.
When two dice are rolled what is the probability of not getting a sum of 12?
The probability of rolling 12 with 2 dice is 1 in 36. The probability of not rolling 12 with 2 dice is 35 in 36.
