    1. Best Answer

      Total number of marbles = 5 + 8 + 4 = 17
      (i) Number of red marbles = 5
      Probability of getting a red marble = (Number of favorable outcomes)/Number of total possible outcomes) = 5/17
      (ii) Number of white marbles = 8
      Probability of getting a white marble = (Number of favorable outcomes)/Number of total possible outcomes) = 8/17
      (iii) Number of green marbles = 4
      Probability of getting a green marble = (Number of favorable outcomes)/Number of total possible outcomes) = 4/17
      Probability of not getting a green marble = 1 – 4/17 = 13/17
