Morphology

improbability = improbable (transparent) = im + probable + ity

Standard noun formation from the adjective 'improbable' (im- + probable) indicating the state or quality of not being probable, which is directly derivable by learners.

Etymology

Improbability comes from the parts im- ('not') and probable ('likely' or 'reasonable'), so an improbability is something 'not likely' to happen or be true.
