WebbBy not replacing the marble after the first draw, the probability of the second draw is affected. The sample space of the second draw has changed, leaving only 4 marbles. The events are dependent. P (green then red) = P (green) • P (red given green occurred) = 3/5 • 2/ 4 = 6/20 = 3/10.

WebbHence, The probability that you draw 5 green marbles in a row if you do replace the marbles after each draw = 0.0194 or 1.94% For the second problem, since we are not replacing the marbles, each draw of a marble, the probability of getting a blue changes since the number of marbles inside the jar changes: 1st draw: 9/(10+3+9) = 9/22
WebbThe sample space for the second event is then 19 marbles instead of 20 marbles. This is called probability without replacement or dependent probability.

So the probability of the second one being red is 2/8 = 1/4. Since the question is asking the probability of BOTH events happening, you multiply the two probabilities. So the answer is (5/9) * (1/4) = 5/36.
