Let X be the set of all possible outcomes. Let A be an outcome.
So, the probability that A occurs is:
As the set of all possible outcomes of the roll of a single die is:
Observe that
Here
because 8 is not in the set sample space. So, the outcome of occurring the number 8 is not possible from the all possible outcomes.
So, the probability must be zero.
In other words,
Therefore,
