Assuming that the die is a regular 1 - 6 die, there is zero chance of you throwing an eight with a single six-sided die.
The probability of rolling an even number is 1/2.
1/2!
The probability is 1.
It is 0.5
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.
The probability of rolling a four on an eight sided octahedron is 1 in 8, or 0.125.

Assuming that the die is a regular 1 - 6 die, there is zero chance of you throwing an eight with a single six-sided die.
The probability of rolling an even number is 1/2.
The probability of rolling a number less than 1 on a standard 6-sided die is zero. It will not happen.
1/2!
The probability is 1.
With a standard 6-sided die, the probability of rolling a prime number is 1/2
It is 0.5
One roll of one normal cube: the answer is 0.
