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 was green?

3/14 for just the purple.
If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
3/15 * 3/14 = ? for both events
