$\text{F. }\frac{1}{6}$
This question is asking us to find the probability of drawing a red marble. The probability of drawing red is equal to the number of red marbles in the bag divided by the total number of marbles in the bag. This gives us: $$P(\text{red})=\frac{2}{2+4+6}=\frac{2}{12}=\frac{1}{6}$$This gives us choice $\text{F. }\frac{1}{6}$
