Answer:
6.9%
Step-by-step explanation:
7 red marbles, 3 blue marbles and 8 green marbles = 18 marbles
P ( green ) = green/total = 8/18 = 4/9
Keep marble
7 red marbles, 3 blue marbles and 7 green marbles = 17 marbles
P ( green ) = green/total = 7/17
Keep marble
7 red marbles, 3 blue marbles and 6 green marbles = 16 marbles
P ( green ) = green/total = 6/16 = 3/8
P (green,green,green) = 4/9*7/17 * 3/8 = 7/102
To the nearest tenth of a percent
.068627451 = 6.8627451% = 6.9%
