An impossible event has probability zero,but if the probability of an event is zero it doesn´t mean that this event is impossible as you can define probability as the LIMIT of (favorable cases/all cases) and this quotient is not necessarly zero

An impossible event has probability 0.
The converse is not true. What is the probability of a real number chosen at random in the interval [0,1] being 0.6? Since this is one number out of an infinite number of real numbers, the probability is 0, but the event is not impossible.

If something is impossible it has a probability of 0.
If something is certain it has a probability of 1
