"Oh thank you Clever Rotchm" said the children,
"We thought maybe there WAS a 'catch' in there eh!"
So the children swapped their box for the second box.
Then the math teacher, holding up the first box said
"There is a 50% chance that this box has twice as many sweets,
but there is a 50% chance that it only has half as many sweets as
that second box, so which box do you want, the first box, or the
second box ?".
"OH WHAT SHOULD WE DO NOW, CLEVER ROTCHM ????" said the children.
