No blue marbles in the bag.
None, if all the marbles that you have are yellow!
3/10 or 0.3 is the probability of picking a purple marble.
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.
1 in 15 chances that the marble will be blue, because there are 15 marbles all together in a bag, and you are only picking one out of it.
The probability of selecting a red marble is 3/9

soory dude or girl but this was just a joke question. but i hope you find what your looking for. by Michael Johnson
Probability is simple. Probability means the number of favorable outcomes over the total amount of outcomes.For example, if I had 15 marbles in a bag. 10 are yellow, and 5 are red. The probability of picking a yellow marble is 10/15, which simplifies to 2/3.
The probability, in one draw, is 6/20 or 30%
The probability of selecting a red marble is 3/9
probability of pulling out a purple marble = 20/85probability of NOT pulling out a purple marble = 1 - 20/85 = 65/85 = 13/17
