What is the probability of rolling the same number on two dice?

We'll assume standard six-sided dice.
The first die rolls... well, whatever it rolls. It doesn't really matter what the specific number is.
The second die can come up any of six different ways. One of those ways is with the same number as the first, the other five are different.
So the chances of rolling two dice and getting the same number on both is 1/6.

What is the probability of rolling the same number when two dice are rolled?
1/6
Three dice are tossed what is the probability that the same number appears on exactly two of the three dice?
The probability is 90/216 = 5/12
If you have 3 fair dice each numbered 1 to 6 what is the chance all three dice show even numbers?
Probability is 1/8 or 0.125 or 12.5% Explanation: A fair dice with six sides (numbers) has a probability of 1/2 of rolling an even number. Note: 1/2 = 3/6, where the dice has 3 even numbers out of six total sides. The probability of three same dice all roll an even number is the probability of one of these (1/2) to the power 3, or (1/2) * (1/2) * (1/2) which equals 1/8.
What is the theoretical probability of not rolling a 2?
1/6= 2 because there is only one 2. Therefore the theoretical probability of not rolling a two is the same as everything but two so 5/6.
There are 36 different outcomes possible when you toss two dice. What is the probability that the two dice will show the same number?
There are 6 different doubles that can be rolled. (They are 1 and 1, 2 and 2, etc.) You have a 6/36 chance of rolling doubles. The fraction 6/36 simplifies (reduces) to 1/6. Your 1 in 6 chance of rolling doubles now needs to be converted to probability. Probability speaks to the "chance" that something will occur. It is expressed as a "pure" number, and the range of probability is from 0 to 1. The probability 0 means that it cannot occur, and the probability 1 means that it will or must occur. Everything else falls in between. If you have a 1 in 6 chance of rolling doubles that translates into a 1 divided by 6 probability, or a 0.1666666... probability that a double will come up.
When rolling five dice what is the probability that all 5 dice will be the same number?
The probability of rolling the same number on five dice is (1/6)4, or about 0.0007716.
What is the probability of having the same number when rolling a dice twice?
If it is a regular dice then the probability is 3/6 that is 1/2
What is the probability of rolling the same number when two dice are rolled?
1/6
What is the probability with 2 dices getting roles on the same number?
The probability of rolling two 6-sided dice and getting the same number on each is 1/32, or "one out of thirty two". This is because there are 6 oppurtunities on each dice, and the probability of getting the same of the 6 oppurtunites on two dice is 6 squared, which is 32.
You roll a dice once what is the probability that you roll an even number?
The same as rolling an odd number... 1:2 or 50% chance.
What are the probabilities of rolling a a five with one dice?
Rolling the dice once will result in any one of the six numbers having the same probability of being up. The probability of getting a '5' = 1/6, the same as getting a '1.' ============================
What is the probability if two cubes whose faces are numbered 1 through 6 will show the same number?
The probability of rolling doubles on a pair of dice is 1 in 6, or about 0.1667.
What is the probability of rolling two dice and getting the same number?
1/6 is the answerAnother Answer:-It is: 1/6*1/6 = 1/36
What are the odds of rolling 6 same numbers in a six sided die?
The probability of rolling the same number six times on a standard die is (1 in 6)5 or 1 in 7776, or about 0.0001286. The reason the exponent above is five instead of six is that the probability of rolling "some" number on one die is 1, so you need to look at the probability of the other five dice matching the first die. It would not matter if you rolled one die six times, or six dice one time. The odds are the same.
What is the probability of rolling an odd number on a 20 sided dice?
Assuming the sides are labelled one to twenty and that all sides are the same shsp and size and that the dice in not biased in any way, then there will be a 50% chance of getting an odd number.
Three dice are tossed what is the probability that the same number appears on exactly two of the three dice?
The probability is 90/216 = 5/12
What are the odds against both dice showing the same numberwhen you toss two dice at the same time?
The probability of both dice showing the same number is 1/6 and the probability of different numbers is 5/6.
