Answer:

Step-by-step explanation:

Total Marbles = 16

Green = 10

Blue = 6

P(G) = 10/16 = 0.625

Since this is probability without replacement then the amount changes for each marble taken out.

After taking one green marble out now there is only

Total marbles = 15

Green = 9

Blue = 6

P(G) = 9/15

So on so forth until your last marble.

P(All Green) = [tex]\frac{10}{16} * \frac{9}{15}* \frac{8}{14}* \frac{7}{13}[/tex] = 1/9 or 0.1111
