Probability quantifies the chance of an event happening, often expressed as a percentage or a fraction. Possibility, on the other hand, simply refers to the potential for something to happen, without quantifying how likely it is.

Probability is a mathematical term used to describe the likelihood of an event occurring. Possibility refers to the chance that something might happen, whether it has a greater or lesser chance. Possibility is a broader concept, while probability is more specific and quantitative.

Probable refers to something that is likely to happen or to be true, indicating a higher degree of likelihood based on evidence or reasoning. On the other hand, possible describes something that can happen or be true but does not necessarily indicate the likelihood; it simply means the outcome or circumstance is not ruled out.
