A bag has 3 red rocks, 4 green rocks, 3 blue rocks, 3 speckled rocks,
and 4 yellow rocks. You randomly pull a rock from the bag, put it
back, and then pull out another one.
What is the probability of getting a green and then a red?

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

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
