Answer:
Number of red marbles = 5
Number of white marbles = 8
Number of green marbles = 4
Total marbles = 17
Probability (of getting a red marble) = Number of red marbles/Total number of marbles = 5/17
Probability (of getting a white marble) = Number of white marbles/Total number of marbles = 8/17
Probability (of getting a marble that's not green) =
Number of marbles that are not green (i.e. 8+5 = 13)/Total number of marbles = 13/17
