wouldn't it be 8/1 unless you pulled the green one on the first draw.

The probability of drawing a blue marble followed by a green marble without replacement is 10 1 ​ . This is calculated by multiplying the probability of drawing a blue marble first by the probability of drawing a green marble second. Specifically, the probabilities are 10 9 ​ for the first draw and 9 1 ​ for the second draw.
