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

based on context clues you gave i'm assuming the answer would be c.

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
