2/6
The probability of rolling a 7 at any time on a single die is zero.
The probability of rolling any single number of a regular die on one roll is one in six, or 1/6, or 0.166666....
impossible
The probability is 1/42.
What do you think? Its a tiny bit very obvious.
The probability of rolling a 5 on a roll of a single number cube is 1/6 (0.1666) as there is only one number 5 on a total of 6 sides on the cube.
If the die is fair then for a single roll, the probability is 1/2.
The probability of rolling an odd number of a standard die is 3 in 6, or 1 in 2, or 0.5.
the probability is 2/6
50%
On a single roll is it 2/3.
It is 0.5
