An impossible event has a probability of 0 (or 0%).
A probability event that is impossible is one that will not happen, i.e. its probability is zero.
An event that zero, or no probability of occuring.
Impossible
From a probability standpoint this is not a true statement. Probability can be equal to zero for an event, indicating that it is impossible. The difference between 'impossible' and 'improbable' from a probability standpoint is that an impossible event has a probability of 0 while an improbable event has a very, very small probability.
An impossible event has a probability of 0 (or 0%).
A probability event that is impossible is one that will not happen, i.e. its probability is zero.
The probability of an impossible event is 0 (zero).
zero
An event that zero, or no probability of occuring.
Impossible
It is an impossible event - which has probability zero.

If the event is truly impossible, it has a zero probability of occurring. The definition of impossible is "not able to occur, exist, or be done," so that means there's no chance of it happening.
If "jmoojn" is the moon then the event has already happened and it was not you. So it is impossible and therefore the probability is 0.
If the probability of an event is zero then that event cannot happen
An event which has a probablility of 1 is one that will definitely happen. Probabilities range between 0 and 1 (0% and 100%) with a probability of zero meaning it is impossible and a probability of one meaning that it is definite. i.e. winning the lottery if you never play has a probability of zero and winning the lottery if you know the correct numbers in advance has a probability of one.
