There are 8 marbles that aren't black, out of a total of 12 marbles, so the probability is 8/12 or 2/3.
Total number of marbles in the bag = 6 + 19 + 5 + 19 + 17 = 66Number of yellow ones = 19If drawing perfectly randomly, then the probability of pulling a yellow one = 19/66 = 28.8% (rounded)

probability of pulling out a purple marble = 20/85probability of NOT pulling out a purple marble = 1 - 20/85 = 65/85 = 13/17
There are 15 blue marbles, 8 yellow marbles and 27 red marbles for a total of 50 marbles. Since there are no green marbles in the lot, It is impossible to pull a green marble from the lot. The is no probability whatsoever! "There just ain't no green ones to pull."
The theoretical probability of randomly picking each color marble is the number of color marbles you have for each color, divided by the total number of marbles. For example, the probability of selecting a red marble is 3/20.

Well, honey, if you're reaching into that bag three times and each time you're pulling out a yellow marble and then putting it back in, the probability of picking a yellow marble each time is 8/21. Multiply that by itself three times because you're picking three marbles, and you get a probability of 512/9261. So, good luck with those yellow marbles, darlin'!
3/10 or 0.3 is the probability of picking a purple marble.
