Explanation:
- First, we need to find the total number of ways to draw 3 balls out of 9 (2 red, 3 blue, 4 black), which can be calculated using combinations. This is denoted as C(9,3) = 84.
- Next, we need to find the number of ways to draw all 3 blue balls out of the 3 blue balls available, which is simply 1.
- Therefore, the probability of drawing all blue balls is the number of favorable outcomes (1) divided by the total number of possible outcomes (84), which gives us 1/84.
Therefore, the correct answer is option 'D' - none of these.
