comment A challenge by R. P. Feynman: give counter-intuitive theorems that can be translated into everyday language
"I have two children. One is a boy born at midnight. What is the probability I have two boys?". If we assume a continuous distribution for the birth time, the event that both the children have been born ad midnight has probability zero. Therefore the answer to this other question should be 1/2. Is this correct?
