The probability of rolling a four on an eight sided octahedron is 1 in 8, or 0.125.
The probability is 0.
Assuming that there are an equal number of even and odd faces on the eight-sided die, then the probability of rolling an even number is simply 4 in 8, or 1 in 2, or 0.5.
That's going to depend on how many numbered sides the "cube" has, and howthey're numbered.If it's literally a six-sided cube, with the faces numbered 1 through 6, then the onlymultiple of 4 anywhere on it is 4, and the probability of rolling the 4 is1/6 or (16 and 2/3) percent.
The probability of rolling a particular face in a 12 sided die is 1 in 12, or about 0.0833.
It is 3/4.
If the faces on the 12 sided die are numbered from 1 to 12, then 1/12.
The probability is 0.
Assuming that the faces of the 20 sided die are numbered 1 to 20, then the probability of rolling a number less than 9 is 8 in 20, or 0.4.
Assuming that there are an equal number of even and odd faces on the eight-sided die, then the probability of rolling an even number is simply 4 in 8, or 1 in 2, or 0.5.
Assuming the 4-sided die is numbered 1 to 4 and the 12 sided one is numbered 1-12, the answer is 4/(4*12) = 1/12
Assuming the numbers are 1-6, the probability is 0.
One roll of one normal cube: the answer is 0.

The probability of rolling a particular face in a 12 sided die is 1 in 12, or about 0.0833.
The probabilities are 1/12, 0 and 0 respectively.
