What is the difference between "probably" and "possibly"? [closed]

Solution 1:

Probably

  • chances of happening are high (or at least not minuscule)

Possibly

  • chances of happening are not zero

Solution 2:

These terms can actually be defined in a reasonably precise way, although they're sometimes used with a bit of liberty.

Let P = probability of event occurring

Probably => 0.5 < P < 1

Possibly => 0 < P << 1 (at least, in everyday speech, though more strictly P could be anything up to 1)

It is evident that in some cases, there is overlap between the two terms.
