\Prob"a*ble\, a. [L. probabilis, fr. probare to try,
approve, prove: cf. F. probable. See {Prove}, and cf.
{Provable}.]
1. Capable of being proved. [Obs.]
2. Having more evidence for than against; supported by
   evidence which inclines the mind to believe, but leaves
   some room for doubt; likely.
         That is accounted probable which has better
         arguments producible for it than can be brought
         against it.                           --South.
         I do not say that the principles of religion are
         merely probable; I have before asserted them to be
         morally certain.                      --Bp. Wilkins.
3. Rendering probable; supporting, or giving ground for,
   belief, but not demonstrating; as, probable evidence;
   probable presumption. --Blackstone.
{Probable cause} (Law), a reasonable ground of presumption
   that a charge is, or my be, well founded.
{Probable error} (of an observation, or of the mean of a
   number), that within which, taken positively and
   negatively, there is an even chance that the real error
   shall lie. Thus, if 3[sec] is the probable error in a
   given case, the chances that the real error is greater
   than 3[sec] are equal to the chances that it is less. The
   probable error is computed from the observations made, and
   is used to express their degree of accuracy.
{The probable}, that which is within the bounds of
   probability; that which is not unnatural or preternatural;
   -- opposed to the marvelous.
