Find the probability for the experiment of drawing two marbles (without replacement) from a bag containing four green, six yellow, and five red marbles such that both marbles are yellow.
A) $\frac { 1 } { 7 }$
B) $\frac { 4 } { 25 }$
C) $\frac { 6 } { 35 }$
D) $\frac { 1 } { 3 }$
E) $\frac { 2 } { 3 }$

The probability of drawing the first yellow marble is 6/15. After drawing one yellow marble, there are 5 yellow marbles left out of 14 total marbles, so the probability of drawing a second yellow marble is 5/14. The combined probability is (6/15) * (5/14) = 1/7.
