Answer:
B. 11/17
Step-by-step explanation:
The total number of marbles in the bag is 34
13 + 9 + 12 = 34
Then you subtract 12 from 34, since you want to know the probability of NOT getting a green marble.
12 - 34 = 22
Then you plug them into the equation:
# of outcomes that satisfy the requirement/ total # of possible outcomes
22/34 = 11/17
