There would be a 7/19 or 36.84% chance of drawing a blue marble from the bag.
7/19
it would be red because the probability is 5/9
There are 8 marbles that aren't black, out of a total of 12 marbles, so the probability is 8/12 or 2/3.
2/9
Probability of drawing a red marble = 4/16 = 1/4 Probability of drawing not a red marble = 1 - 1/4 = 3/4
There is a probability of 3 that it will be blue.
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.
it would be red because the probability is 5/9
The probability is 0.56
There are 8 marbles that aren't black, out of a total of 12 marbles, so the probability is 8/12 or 2/3.

2/9
Probability of drawing a red marble = 4/16 = 1/4 Probability of drawing not a red marble = 1 - 1/4 = 3/4
There is a probability of 3 that it will be blue.
The probability of picking a green marble from a box that only contains blue marbles is zero.
2/6
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 13 marbles in total. The order is specified.P(1st is white and the 2ndis purple) = (7/13)(6/12) = (7/13)(1/2) = 7/26.
