Answer:
4/105
Step-by-step explanation:
Total number of marbles: 2 + 4 + 1 + 8 = 15
Number of blue marbles: 4
First drawing:
p(blue marble) = 4/15
Now there are 14 marbles left.
Number of green marbles: 2
p(green marble) = 2/14 = 1/7
p(blue then green) = p(blue) * p(green) = 4/15 * 1/7 = 4/105
Answer: 4/105
