Explanation:

Step1: Calculate total number of marbles

The total number of marbles is the sum of green and blue marbles. So, $5 + 4=9$.

Step2: Find probability of not - green

The marbles that are not green are blue. There are 4 blue marbles. The probability $P$ of an event is given by the number of favorable outcomes divided by the total number of outcomes. So the probability that a marble drawn is not green is $\frac{4}{9}$.

Step3: For the dice problem

The probability of getting a 12 when two fair dice are tossed is $P(12)=\frac{1}{36}$. The probability of not getting a 12 is $P(\text{not }12)=1 - P(12)$.

Step4: Calculate the probability

$P(\text{not }12)=1-\frac{1}{36}=\frac{36 - 1}{36}=\frac{35}{36}$.

Answer:

1. D. $\frac{4}{9}$
2. D. $\frac{35}{36}$
