There are 7 marbles, including 3 green ones, so at the start, there is a 3/7 chance of getting a green marble.
Assuming you did get a green one, there are now 6 marbles left, with 2 blue marbles, so there is a 2/6 chance of taking a blue marble.
Given that both have to happen, you must multiply each probability, hence the total probability is 3/7 x 2/6, or a 1/7 chance.

Answer:
$2.25 per ft² (I think)
Step-by-step explanation:

Then you get 9.6 and 7.35
Subtract 7.35 from 9.6 and get 2.25
