A: In Mahjong , what is the chance to get a hand that allows a player to finish on their first turn?

JanNote: I am basing this answer on Japanese Mahjong rules; Chinese rules will probably lead to a different outcome. Tenhou, Chihou or Renhou hands must be valid hands, i.e. they must satisfy the requirement of having four groups of three and one pair; except for Chiitoi (seven pairs) and Kokushi M...

However ... at least we found during the last month that the "newly" bought conductivity electrodes are not precise enough. :'D

Oh tell me about it
@pH13-YetanotherPhilipp Bah psssht, not precise enough in Germany?
