Let ‘x’ be the number on the first dice. ‘Y’ be the number on second dice. We have to find the probability that the sum is 4 or higher i.e. (x + y) >= 4 Total number of possible results from two six-sided dice = 6 × 6 = 36. The possible results that the sum is lower than 4 is: (1,1) (1,2) and (2,1). The probability that the sum is lower than 4 = 3/36 = 1/12. The probability that the sum is 4 or higher = 1 - (1/12) = 11/12 Therefore, the probability that the sum is 4 or higher is 11/12. If you roll two fair six-sided dice, what is the probability that the sum is 4 or higher?Summary: If you roll two fair six-sided dice, the probability that the sum is 4 or higher is 11/12. Your probabilities are wrong. For each value of die 1, there are 6 possible values of die 2, the available scores for a roll of two dice are: (7 is the most likely score) So, out of the 36 total possible outcomes, 33 of them have a value of 4 or higher, or 33:36, or 11:12

It’s very common to find questions about dice rolling in probability and statistics. You might be asked the probability of rolling a variety of results for a 6 Sided Dice: five and a seven, a double twelve, or a double-six. While you *could* technically use a formula or two (like a combinations formula), you really have to understand each number that goes into the formula; and that’s not always simple. By far the easiest (visual) way to solve these types of problems (ones that involve finding the probability of rolling a certain combination or set of numbers) is by writing out a sample space. Dice Roll Probability for 6 Sided Dice: Sample SpacesA sample space is just the set of all possible results. In simple terms, you have to figure out every possibility for what might happen. With dice rolling, your sample space is going to be every possible dice roll. Example question: What is the probability of rolling a 4 or 7 for two 6 sided dice? In order to know what the odds are of rolling a 4 or a 7 from a set of two dice, you first need to find out all the possible combinations. You could roll a double one [1][1], or a one and a two [1][2]. In fact, there are 36 possible combinations. Dice Rolling Probability: StepsStep 1: Write out your sample space (i.e. all of the possible results). For two dice, the 36 different possibilities are: [1][1],
[1][2], [1][3], [1][4], [1][5], [1][6], Step 2: Look at your sample space and find how many add up to 4 or 7 (because we’re looking for the probability of rolling one of those numbers). The rolls that add up to 4 or 7 are in bold: [1][1], [1][2], [1][3], [1][4], [1][5], [1][6], There are 9 possible combinations. Step 3: Take the answer from step 2, and divide it by the size of your total sample space from step 1. What I mean by the “size of your sample space” is just all of the possible combinations you listed. In this case, Step 1 had 36 possibilities, so: 9 / 36 = .25 You’re done! Two (6-sided) dice roll probability tableThe following table shows the probabilities for rolling a certain number with a two-dice roll. If you want the probabilities of rolling a set of numbers (e.g. a 4 and 7, or 5 and 6), add the probabilities from the table together. For example, if you wanted to
know the probability of rolling a 4, or a 7:
Probability of rolling a certain number or less for two 6-sided dice.
Dice Roll Probability TablesContents: Probability of a certain number with a Single Die.
Probability of rolling a certain number or less with one die.
Probability of rolling less than certain number with one die.
Probability of rolling a certain number or more.
Probability of rolling more than a certain number (e.g. roll more than a 5).

Comments? Need to post a correction? Please Contact Us. What is the probability of getting a 4 when a dice is rolled?The probability of getting a 4 when a die is rolled is 1/6.
How many ways are there to roll a 4 with 2 dice?Originally Answered: If two dices are rolled, what is the probability the combined total is 4? There are 36 possible outcomes when rolling 2 dice. There are three ways of getting a total of four, (1,3), (3,1), and (2,2). So the probability is 3/36 = 1/12.
What is a sum of 4?The Sum of 4 is a concept that emphasizes the fact that there are multiple, if not infinite, ways to reach certain results, goals, dreams, or destinations. It's like the classic idiom: There is more than one way to cook an egg…. There is no single way of doing something….
What is the probability the dice sum to 4 or greater?If you roll two fair six-sided dice, the probability that the sum is 4 or higher is 11/12.
