15/56

Explanation:

The odds of the first marble being green are # 5/8# because there are 5 green marbles and 8 total marbles.

After one marbles is removed the odds of the second marble being blue are #3/7# because there are 3 blue marbles and now 7 total marbles.

Multiply these odds to find the total odds.

# 5/8 xx 3/7 = 15/56#
