What is the probability of rolling two different numbers on two dice?
8 Answers. The probability of rolling a specific number twice in a row is indeed 1/36, because you have a 1/6 chance of getting that number on each of two rolls (1/6 x 1/6). The probability of rolling any number twice in a row is 1/6, because there are six ways to roll a specific number twice in a row (6 x 1/36).
What is the probability of rolling two even numbers?
Probability of both even is 12×12=14. Given they are both even there are 3 possible even numbers: 2,4,6.
What is the probability of rolling a 1 or a 5 on two dice?
Hence the probability that at least one shows a 1 or 5 is 1−(2/3)2=5/9.
What is the formula for calculating probability?
How to calculate probability
- Determine a single event with a single outcome.
- Identify the total number of outcomes that can occur.
- Divide the number of events by the number of possible outcomes.
What is the probability of an even number on the 1st roll or a sum of 2?
Of these 36 possible combinations (add up all the ‘ways’), 18 of them will produce an even number. So the probability of getting an even number is 1 out of 2… 1/2… 50%.
What is the probability of getting a number greater than 3?
Calculate the probability of getting a number that is either even or greater than 3. So the probability that your roll is either going to be an even number OR a number greater than 3 is 1/2.
