35:1 or 35 to 1.
"Snake eyes"
The probability for a total of two on two dice are the product of the chances
on each die. You will get one spot an average of one time in six on
one die, so the chances are one in 6. The same is true on the second
die, so the chance of both happening together on one roll are 1/6 x 1/6
or 1/36.
"On average,"1 out of 36 times you will get "snake eyes," so 35 out
of 36 times you will not.
That make the odds AGAINST equal 35:1 or 35 to one.

The odds of not rolling a 1 or 2 with two dice is 35 in 36. The odds of doing that 25 times in a row is (35/36)25 or about 0.4945Note: The odds of not rolling a 1 is zero, so the answer degraded to the odds of not rolling a 2.===================================Opinion #2:-- There are 36 possible outcomes when 2 dice are rolled.-- Only one of the outcomes is a 2.-- So the probability of NOT rolling a 2 with 2 dice is 35/36 .-- In 25 consecutive rolls, the probability of never rolling a 2 is (35/36)25 = 49.45% .-- The 'odds' are 1,011 to 989 against it.
Assuming you are rolling a six-sided dice, it is 1/3 for one dice and 2/3 for two dice.
The probability of rolling doubles with two dice is 1 in 6, or about 0.167.
The odds of rolling a 7 with two dice is 6 in 36, or 1 in 6.Two six-sided dice will yield 36 different possible combinations in one roll. Note that rolling 1 and 6 is not the same as rolling 6 and 1. Yes, they both equal 7, but for the purposes of determining probability, each throw is unique. There are 6 possible ways to throw a 7, and they are 1-6, 2-5, 3-4, 4-3, 5-2, and 6-1. With 36 different possible outcomes, that means that 6 in 36 of those outcomes results in a 7. The odds of getting a 7 are 6 in 36, or 1 in 6 (reducing the two terms).We sometimes see the terms "odds" and "probability" interchanged, but it is important to distinguish them mathematically.
