Answer: 12/17

Step-by-step explanation:

This is an example of probability with replacement

n(red) = 3

n(green) = 4

n(blue) = 3

n(speckled) = 3

n(yellow) = 4

Total = 17

The probability of getting a green = number of green / total number

That is

p(green) = 4/17

Also

p(red) = 3/17

" and " in probability means multiplication , therefore:

the probability of getting a green and then a red will be

4/17 x 3/17 = 12/17
