A bag contains 4 red marbles, 3 blue marbles and 7 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that all three marbles drawn will be green?

Respuesta :

Answer:

10% of all three marbles drawn being green

Step-by-step explanation:

4 red marbles + 3 blue marbles + 7 green marbles = 14 total marbles

7/14 marbles are green so 1/2 chance

then, each time you pick up a marble, the chance for the marble decreases since you're not putting it back

7/14 x 6/13 x 5/12 = 0.09615

round to nearest tenth

0.10 or 10%
