are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that
all three marbles drawn will be green?

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:

[tex]P= \frac{1}{3}* \frac{1}{3}*\frac{1}{3}[/tex]

We get a probability of:

[tex]P= \frac{1}{27}[/tex]

This converts to a percentage of:

[tex]\frac{1}{27}= 0.037 \\ 0.037*100= 3.7%[/tex]

We get a percentage of 3.7%
