Shanghai Dart Tournament
At a Shanghai dart tournament, Henry asked a referee about the rounds played by Jack and Jill.
“I don’t know exactly how many rounds they played before they left, but they flipped a coin each time to see who would go first, and I know that Jack won the toss four times,” said the referee.
“Thanks,” said Henry and pulled out a small notebook and a pen from his shoulder bag. “I’ll work it out.”
