SUMMARY
The probability of picking a red ball, followed by a blue ball, and then another red ball from a bag containing 5 red, 6 green, and 9 blue balls, without replacement, is calculated as follows: (5/20) * (9/19) * (4/18). This calculation is correct, confirming that the methodology for determining the probability is sound and accurately reflects the scenario presented.
