To find the probability that a blue marble will NOT be selected, first calculate the total number of marbles: 9 red + 6 blue + 7 green + 11 yellow = 33 marbles. The number of non-blue marbles is 9 red + 7 green + 11 yellow = 27 marbles. Therefore, the probability of NOT selecting a blue marble is 27/33, which simplifies to 9/11.
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
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.

To find the experimental probability of choosing a green marble, first calculate the total number of marbles: 7 red + 9 yellow + 14 green + 10 purple = 40 marbles. The probability of choosing a green marble is the number of green marbles divided by the total number of marbles, which is 14 green / 40 total = 0.35. Thus, the experimental probability of choosing a green marble is 0.35, or 35%.
3/10 or 0.3 is the probability of picking a purple marble.
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'!
