What are the odds of not rolling a 1 or 5 with 6 dice?

Since there is a 2/3 chance of not rolling a 1 or a 5 for each die, we see that (2/3^6) is the chance of not rolling either number on 6 dice. That is 64/729, so the odds of actually rolling a 1 or 5somewhere among the 6 rolls is (729–64)/729 = 91.22%.

What are the odds of not rolling a 1 with 6 dice?

And so on... the probability of not rolling a 1 if you roll a dice six times is 5/6 * 5/6 * 5/6 * 5/6 * 5/6 * 5/6 * 5/6. Another way to write this is (5/6)^6. The answer here is 0.335.

What are the odds of not rolling a 1?

So the probability of NOT rolling a 1 is 25/36. The opposite (the “complement”) of “NOT rolling a 1” is “rolling AT LEAST one 1”.

What are the odds of not rolling a 6 with 5 dice?

The probability of a fair six-sided die not rolling a 6 is 5/6. If you throw 5 such die, the probability of all coming up not 6 is (5 / 6) to the 5th power. So, the probability of at least one 6 is 1 - ((5 / 6) ** 5) = about 0.598.

What is the probability of a dice showing a 1 or 5?

Since there are six possible outcomes, the probability of obtaining any side of the die is 1/6. The probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6, and so on.

Math puzzle - Rolling dice 6 times

What is the hardest number to roll on a 6 sided dice?

Dice Roll Probability

There's only one combination that yields a total of 2—when each die displays a 1. Likewise, there is only one combination that yields a total of 12—when each die displays a 6. They are the least likely combinations to occur.

What are the odds of rolling a 6 with 1 or 2 dice?

If you use the above graphic and count the number of times is 6 appears when two dice are rolled, you will see the answer is eleven. Eleven times out of 36 or 30.5 %, slightly less than the 33.3% (2/6). When you roll two dice, you have a 30.5 % chance at least one 6 will appear.

What are the odds of rolling 1 through 6 with 6 dice?

(1/6)⁶ = 1/46,656 =~ 0.00002143 = 0.002143%. which gives the odds for how many of the 6 rolls end up on the desired value.

What are the odds of rolling a 1 in 6 rolls?

For getting a 1 on six dice as you describe, take this number to the power 6, to get 0.00559 or 0.559%. For five dice out of six, the probability is 6 * 125/216 * (91/216)^5 = 0.0193... The chance of exactly n dice getting a 1 out of three rolls would be: 6Cn * (125/216)^(6-n) * (91/216)^n.
