There is a 1 in 2 chance, so 1/2.
If it is a fair die that is rolled once, then the probability is 2/3.
5/6 = 83.3%
The probability is 1, if the dice are rolled often enough.
It is 1/2 if it is a fair number cube which is rolled once.
The probability of a one being rolled in a fair die is 1 in 6, or 0.1666... . The probability of a one not being rolled is 5 in 6, or 0.8333... . The probability, then, of exactly one one being rolled in nine rolls is 1 in 6 times 5 in 6 to the 8th power, or about 0.0388.
If it is a fair die that is rolled once, then the probability is 2/3.

The probability is 1, if the dice are rolled often enough.
It is 1/2 if it is a fair number cube which is rolled once.
it depends on how many numbers are on the number cube. if it only goes to 6, then the probability is 1/6. if it goes to 8 then the probability is 2/8. and so on and so on...
The probability of a one being rolled in a fair die is 1 in 6, or 0.1666... . The probability of a one not being rolled is 5 in 6, or 0.8333... . The probability, then, of exactly one one being rolled in nine rolls is 1 in 6 times 5 in 6 to the 8th power, or about 0.0388.
The probability that 14 is rolled at least once is 1 - 5.5*10-32 which, for all intents and purposes, can be treated as 1.
1 out of 2
If two dice are rolled once, the probability is 30/36 = 5/6
The probability of getting 3 or more heads in a row, one or more times is 520/1024 = 0.508 Of these, the probability of getting exactly 3 heads in a row, exactly once is 244/1024 = 0.238
