A bag contains two blue, three purple, four yellow, two red, three green and one orange marbles.

What is the conditional probability that, without replacement, the second marble is purple given that the first marble is green?

if the first is green, there are still 14 marbles left, and the purples are still all there, so
prob = 3/14
