a bag contains 8 yellow marbles, 16 red marbles, 3 blue marbles, and 3 black marbles. what is the probability of drawing a black marble out of the bag?

Where are the choices ? ? There are 30 marbles in the bag, and 3 of them are black. So the probability of getting a black with a random draw is 3/30 = 10% .

Just add the total number of marbles up and convert it into a fraction and simplify if needed. There are 3 black marbles, and a total of 30. So the answer would be 3/30 or 1/10. Hope this helped.

3/30 =1/10
