Do you have the tooth fairy where you live? We definitely did in the UK but apparently it’s not a thing in China.
Side note: Elise made a wish that the tooth fairy left more than 20rmb. The tooth fairy left 21! What are the chances?!
@Omrrc everything else being equal - statistically there is a lot more chance that more than 20 will be left than less.
UNLESS the 'rmb' can be broken down into infinite parts - in which case I think the chances are equal (Infinity on both sides) - but I might be wrong - my Cantorian maths breaks down on occasions.
