if there is a jar containing 5 red marbles 6green and 4 blue what is the probability off not chossing a blue marble
Number of different possible choices = 8 + 6 + 9 = 23Number of available successful choices (blue marbles) = 6Probability of success = 6/23 = 0.26087 = 26.087 %(rounded)
3/5
There are a total of 25 Marbles The chances are 3 out of 25 drawing a Red marble. 3/25 = 12% chance of drawing a red marble
1 in 7
it depends how many blue marbles there are and how many marbles total.
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.
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
There is a probability of 3 that it will be blue.
if there is a jar containing 5 red marbles 6green and 4 blue what is the probability off not chossing a blue marble
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
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.
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 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.
