The first marble is the independent event because its probability is only based on the sample space of the bag. The second marble is the dependent event because its probability is based on the sample space of the bag which has now been changed by the first marble.
The outcome is that you have pulled a marble out of the bag.
The probability of rolling a number greater than 4 is 2/6, that is, 1/3. For the probability of pulling out a red marble, more data has to be known. Just put the number of red marbles in the numerator, the total number of marbles in the denominator. Finally, multiply the two probabilities.
If you reach into the bag, grasp, and withdraw your hand, the probability of pulling something out is about 100%.
