This week we are going to the Garden of Eden for a riddle penned by the British economist, writer, and bridge expert Hubert Phillips. Get ready for some rock-paper-scissors in paradise.
PROBLEM
Adam and Eve play rock-paper-scissors 10 times. You know that:
Adam uses rock three times, scissors six times, and paper once.
Eve uses rock twice, scissors four times, and paper four times.
There are no ties in all 10 games.
The order of games is unknown.
Who wins? By how much?
HINT
It can be tricky to figure out the solution just by looking at the list of information—grab a pad and pen.
