On any roll of two dice there are 36 possible results: 1-1, 1-2, 1-3 and so on to 6-6. Of those, only six add up to 7 (1-6, 2-5, 3-4, 4-3, 5-2, 6-1), so for a single throw, your odds are 6 in 36, the same as 1 in 6 or a 16.67% chance. For two consecutive throws, you take 1 in 6 and multiply it by 1 in 6. That gives you a 1 in 36 chance (2.78%).
You can calculate the odds of rolling, say, 20 consecutive "sevens" the same way by taking the base chance, 1 in 6 (1/6) and raising it to the power of 20... slim odds indeed... one chance in 3,656,158,440,062,976 ! The exponent is always the number of consecutive events.
That depends on whether you roll it twice or not...
one fourth
Rolling it once there is a 1 out of 6 chance - because there is 6 numbers on a dice and one of them is three. so rolling it twice would be a 2 out of 12 chance / 0.16 / 16% chance
There are four outcomes possible. Both even, both odd, and one of each twice. So, in one roll, it looks like your chances are 1 in 4. Is that what you are after?

All of these scenarios are a bad deal. You could most easily roll a 7 twice in a row, so that would be the best scenario.
The probability is 1/6.
For 3 you need 1+2, but for 5 you can have 1+4 or 2+3 so you have twice as many chances for 5.

The odds of rolling a 7 are 1/6. The odds of rolling two in a row are 1/36. The odds of rolling an 11 are 1/18. The odds of rolling two in a row are 1/324. The odds of rolling doubles are 1/6. The odds of rolling double twice in a row are 1/36.

Rolling 2 twice in a row in the first two rolls is 1/6*1/6 = 1/36. But rolling 2 twice eventually is as close to certainty as you can get.
The chance of rolling a 6 twice in a row, on a six-sided die, is 1 in 36 or 2.78%. The number of possible different results for rolling a six-sided die twice is 6 squared (6 times 6), or 36, therefore the probability of getting any one of the possible results is 1 out of 36.
