Answer 1

D. 25/30

Explanation:

add up all the colored marbles for your denominator.

9+9+5+7= 30

so since there are 5 green marbles, you'd subtract the 5 from the 30 total to show how the volunteer could be on any other team than green.

30-5=25

Therefore, the probability that a volunteer is assigned to a team other than the green team is 25/30.

(which could be simplified to 5/6, but that doesn't seem to be an answer for you)

hope this helped & good luck
