if you pick one marble at random, the odds are 17/(42+17+27) or 17/86 or about 20%
The probability of picking a green marble from a box that only contains blue marbles is zero.
7/15 for blue marbles and 8/14 for the purple marbles this is dependent probability
Probability of drawing a red marble = 4/16 = 1/4 Probability of drawing not a red marble = 1 - 1/4 = 3/4
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.
None, if all the marbles that you have are yellow!
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.
3/10 or 0.3 is the probability of picking a purple marble.
The probability of picking a green marble from a box that only contains blue marbles is zero.
7/15 for blue marbles and 8/14 for the purple marbles this is dependent probability
11 marbles total and 6 are blue so probability is 6/11
0No blue marbles in the bag.
The answer is dependent on whether of not you replace the marbles in the jar. If you do, the probability of drawing a red marble is 9 in 15 or 60%, every time. If you do not replace the marbles, the probability of drawing a red marble is 2 in 8 or 25%.
1 in 7
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.
Probability of drawing a red marble = 4/16 = 1/4 Probability of drawing not a red marble = 1 - 1/4 = 3/4
probability of pulling out a purple marble = 20/85probability of NOT pulling out a purple marble = 1 - 20/85 = 65/85 = 13/17
