Answer:
0.0857
Step-by-step explanation:
What we need is, B R -G, successively. We do not add each probability, but multiply them.
P(1st marble is B) = 6 / 16
P(2nd marble is R) = 4 / 15
*your sample space decreases because you took one marble already before, the Blue one
P(3rd marble is not Green) = 12/14
** it's 12 because you took 2 non-Green marbles before
*** it's 14 because you took 2 marbles before
To arrive at the final answer, just multiply all probability.
