possibility vs. probability

the dictionary defines possibility as the potential for favorable or interesting results and probability as the likelihood that a given event will occur

and potential is defined as latent, capable of being but not as yet in existence; while likelihood is defined as the prospect or likeliness of a given event occurring

vastly different words that have been used interchageably, when in fact, possibility is passive & potential is active

more importantly, when faced with a choice, there is always possibility, but it's in our choosing that the potential is kindled
