"The raven paradox, also known as Hempel's paradox or Hempel's ravens, is a paradox arising from the question of what constitutes evidence for a statement. Observing objects that are neither black nor ravens may formally increase the likelihood that all ravens are black – even though, intuitively, these observations are unrelated."

Had fun with this one! Always thought this Paradox was a bit strange, and I remember learning about it in statistics class a while back, so I gave it a shot! :)
