Answer:

Inevitable the something is bound to happen, it therefore has a 100% probability it will happen.

Probable, likely means there's a big chance that an event will happen.

Possible we mean there is a non-zero likelihood of that outcome

Unlikely means there's a small chance that an event will happen.

Impossible It will never happen. The event has no chance to happen.
