Find the number of cases in which none of the digits show a '6'. i.e. all three dice show a number other than '6', 5×5×5=125 cases. Total possible outcomes when three dice are thrown = 216. The number of outcomes in which at least one die shows a '6' = Total possible outcomes when three dice are thrown - Number of outcomes in which none of them show '6'. =216−125=91 The required probability = 91/256Related questions
