A marketing research company has been engaged by a mobile app development company to conduct a survey on the mobile Operation System (OS) preference of Male and Female mobile users. A survey was conducted on 500 randomly selected mobile users and following is the result: Mobile OS Robot Gender Male Female iOX Wins 134 80 45 63 128 50 Assume the survey result is a good representation of the population. A user is randomly selected from the population. Calculate, leaving your answers as fractions: a) The probability that a randomly selected mobile user is a female and prefers iOX. b) The probability that a randomly selected mobile user who prefers either iOX or Wins is a female. c) The probability that a male mobile user prefers either Robot or Wins.
