3 in 6, or 1 in 2, or 0.5.
It is 1 (a certainty) if you roll it often enough. For a single roll of a fair die, the probability is 1/6.
0.25 ( P = 0.5 each time)
One out of two
1 out of 2 if the die is six-sided.
With a fair die it is 5/6.

3/6
It is 0.5
0.25 ( P = 0.5 each time)
5 out of 12
It is 0.5
One out of two
1 out of 2 if the die is six-sided.
Since there is only one even prime, 2, the probability of rolling a 2 with one die is 1 in 6.
1 out of 2
The probability of rolling a number on a die is 1 out of the number of sides on the die. So, for a six sided die, the probability of rolling a 4 is 1/6. The probability of rolling a 4 or a 5 becomes 2/6 or 1/3. This is because there are two acceptable outcomes out of six. So when finding the probability of rolling a number less than x on a y sided die, it becomes x-1 / y. It is x-1 because the outcome is to roll less than the number, not less than or equal.
With a fair die it is 5/6.
