Given the word problem, we can deduce the following information:
1. Fernando picks a marble at random.
2. Without putting the first marble back, he picks a second marble at random.
To determine if the events are dependent or independent, we first note that dependent events influence the probability of other events, while independent events do not affect one another.
Since Fernando picks a marble without putting the first marble back, the probability of the second pick is affected.
Therefore, the answer is dependent.
