We will assume that the bag contains 11 marbles (this is not a trick question!), so 4 are blue and 7 are not blue, so the probability of a color other than blue is 7/11.
it depends how many blue marbles there are and how many marbles total.
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.
probability of pulling out a purple marble = 20/85probability of NOT pulling out a purple marble = 1 - 20/85 = 65/85 = 13/17
it depends how many blue marbles there are and how many marbles total.

The probability of drawing a white marble is .46
Probability of drawing a red marble = 4/16 = 1/4 Probability of drawing not a red marble = 1 - 1/4 = 3/4
if there is a jar containing 5 red marbles 6green and 4 blue what is the probability off not chossing a blue marble
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.

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 11+10+17+15+3=56 marbles in total. Of those marbles, 11 are blue and 17 are red, so there are 11+17=28 blue and red marbles. Therefore the probability of choosing a blue or red marble is 28/56=.5, or 50%.
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.
The probability of choosing a green marble from this jar would be 6/15. You get this answer by adding up the sum of all the marbles.
