"Probability is the chance that something will happen - how likely it is that some event will happen.
Sometimes you can measure a probability with a number like "10% chance of rain", or you can use words such as impossible, unlikely, possible, even chance, likely and certain."
I.e between zero and one inclusive, and zero is a valid probability.
"Probability is the measure of the likeliness that an event will occur.[1] Probability is quantified as a number between 0 and 1 (where 0 indicates impossibility and 1 indicates certainty)."

"Probability is the likelihood of something happening in the future. It is expressed as a number between zero (can never happen) to 1 (will always happen)."

Impossible things are not probable and they do not have a probability. Zero probability relates to that which is statistically impossible but not impossible in reality. |
Nope. See your references' definitions. They explicitly defined impossibility as probability zero and vice versa with no caveats. Real word, your fantasy world, World of Warcraft; probability zero occurs and means impossibility. E.g. "The probability that Joe will ever get a clue is zero. It will never happen."
