What is the probability of rolling a sum of four on a standard pair of six sided dice?

What is the probability of rolling a 4 on a standard 6 sided die?

6 Sided Dice probability (worked example for two dice).

Two (6-sided) dice roll probability table.

Roll a… Probability
4 3/36 (8.333%)
5 4/36 (11.111%)
6 5/36 (13.889%)
7 6/36 (16.667%)

What is the probability of rolling a 4 on a 4 sided dice?

Edited: You can’t roll 0 on a four sided die, and the distribution of the outcomes are different. To take the extreme example: With one die you have a 25% chance to have an outcome of 4. With four dice, you need to succeed at a 25% chance to roll a 1 four separate times, or (1/4)4 , which is about 0.4%.

When a standard pair of six sided dice are rolled what is the probability of getting a 7?

For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.

What is the probability that you will roll a sum of six?

Probabilities for the two dice

Total Number of combinations Probability
4 3 8.33%
5 4 11.11%
6 5 13.89%
7 6 16.67%

What is the probability you roll a sum of 5?

To find the probability determine the number of successful outcomes divided by the number of possible outcomes overall. Each dice has six combinations which are independent. Therefore the number of possible outcomes will be 6*6 = 36. The probability of rolling a pair of dice whose numbers add to 5 is 4/36 = 1/9.

What is the probability of getting a sum greater than 4?

1 Expert Answer

So in a single roll the probability of getting a number greater than 4 is 2/6 = 1/3.

How many different outcomes are possible when rolling two 4 sided dice?

Note that there are 36 possibilities for (a,b). This total number of possibilities can be obtained from the multiplication principle: there are 6 possibilities for a, and for each outcome for a, there are 6 possibilities for b. So, the total number of joint outcomes (a,b) is 6 times 6 which is 36.

How many different outcomes are possible for the product of when two 4 sided dice are rolled?

When two dice are rolled, there are now 36 different and unique ways the dice can come up. This figure is arrived at by multiplying the number of ways the first die can come up (six) by the number of ways the second die can come up (six).
