There are 6 green, 8 red, and 6 yellow marbles in a bag. you choose a marble without looking, put it aside, and then choose another marble without looking. use the multiplication rule to find the specified probability, entering it as a fraction. find the probability that you choose a red marble, followed by a yellow marble, followed by a green marble. the probability that you choose a red marble, followed by a yellow marble, followed by a green marble is

Step-by-step explanation:

Total number of marbles in the bag = [ 6 green + 8 red + 6 yellow ] = 20

Then probability of choosing red marble = 8/20

total number of remaining marbles = 19

Then probability of choosing yellow marble = 6/19

total number of remaining marbles = 18

Then probability of choosing green marble = 6/18

Hence required probability that you choose a red marble, followed by a yellow marble, followed by a green marble

Hence final answer is

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
