[AI-generated answer — Bot GPT 3.5]

First, let's calculate the probability of picking a red cube on the first pick.

Total number of cubes = 8 (red) + 3 (yellow) + 5 (green) = 16
Probability of picking a red cube on the first pick = 8/16 = 1/2

Now, if Magan picked a red cube on the first pick and kept it, the total number of cubes remaining would be 15.

Number of red cubes remaining = 8 - 1 = 7
Total number of cubes remaining = 15

Therefore, the probability of picking another red cube on the second pick = 7/15

Multiplying the probabilities of both events:
Probability of picking a red cube on the first pick and another red cube on the second pick = (1/2) * (7/15) = 7/30 or approximately 0.2333 or 23.33% probability.
