worty [1.4K]

Answer:

3.7%

Step-by-step explanation:

We know that from this situation, the probability of drawing a single green marble is 1/3. However, to find the probability of drawing 3 green marbles, we will need to do:

P= \frac{1}{3}* \frac{1}{3}*\frac{1}{3}

We get a probability of:

P= \frac{1}{27}

This converts to a percentage of:

\frac{1}{27}= 0.037 \\ 0.037*100= 3.7%

We get a percentage of 3.7%

C. 3/5
The definition of terminating decimal is that it’s an answer that come to an end after a few decimal places. When looking at a b and d their denominators are 7 and 3 which will give answers with a never ending amount of decimals. This makes them nonterminal decimals. So the answer is c because it has a decimal place and it can give a final answer
