The factors of 20 on a die are: 1,2,4,5
Therefore it is a 4 out of 6 chance you will roll one of the factors. In simplest form, a 2 out of 3 chance or 66 2/3 chance.
50%
Assuming the numbers on the die are 1, 2, 3 and 4, the probability is 1.
The probability of rolling a particular face in a 12 sided die is 1 in 12, or about 0.0833.
The probability of rolling an odd number of a standard die is 3 in 6, or 1 in 2, or 0.5.
The probability of rolling a four on an eight sided octahedron is 1 in 8, or 0.125.
