You have 20 marbles in total. The probability to draw a blue marble is 5/20 = 1/4 = 0.25. The probability to draw a red marble is 6/20 = 0.3. The probability to draw a green marble is 9/20 = 0.45. If two marbles are drawn at random without replacement and one at a time, then the probability that one is red and another is blue is 0.25x0.3 = 0.075. The probability for blue and green is 0.25x0.45 = 0.1125. The probability for red and green is 0.3x0.45=0.135.
