1/6. With two dice there are 36 possible outcomes six of which are doubles 6/36= 1/6.
6:5
Assuming they are fair dice that are numbered 1 to 6, the probability is 2/36 = 1/18
With one roll of three dice, the probability is 7/8.
It is 5/6.
If you roll them often enough then the probability is 0. For just one roll, the probability is 35/36.
If you roll a pair of fair dice 25 times, the probability of rolling a double six at least once is just above 50% (50.55%).
For a single roll of a pair of fair dice, the answer is 1/36.

The probability is 1/2.
Assuming they are fair, regular dice, the probability is 1/18.
It is 1/3.
It is 1: if you roll the die often enough. On a single roll of a fair die, the probability is 1/6.
Assuming they are fair dice that are numbered 1 to 6, the probability is 2/36 = 1/18
With one roll of three dice, the probability is 7/8.
It is 5/6.
It is 6/36 = 1/6.
