you hold a bag filled with 7 green, 5 red, and 8 blue marbles. how would you calculate the probability of selecting first a green marble, then a red one, if you do not replace the first marble drawn before selecting the second?

the total amount of marbles you have is 20 and since u are selecting green first it would be 7/20 and for the red u would subtract one from the total so it would be 5/19 and then u multiply those two together
