Answer: D.4/7

Explanation:

First, we will find out how many marbles are in the bag.

3 red + 1 blue + 4 yellow - 1 red = 2 red + 1 blue + 4 yellow = 7 marbles

Now, we will put wanted outcomes over possible outcomes.


\displaystyle \frac{\text{wanted outcomes, yellow marbles}}{\text{possible outcomes, marbles in the bag}} =\frac{4\text{ yellow}}{\text{7 marbles}} =\text{D. 4/7}
