360

Step-by-step explanation:

If we originally have 9 red cubes, 5 green cubes, and 11 blue cubes, if we add these, we have to:

9 + 5 + 11 = 25

This means that the probability of network cubes of 9/25, now without 1000 pulls, would be:

1000 * 9/25 = 360

That means that about 360 red cubes are expected, probably
