  ## Question
  
  ### Solution
  
  Correct option is
  
  m /2m–1
  
  Let A denote the event that there is an odd man out in a game. The total number of possible cases is 2m. A person is odd man out if he is alone in getting a head or a tail. The number of ways in which there is exactly one tail (head) and the rest are heads (tails) is
  
  .
  
  Thus, the number of favorable ways is m + 2m. Therefore,
