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.
To find the experimental probability of choosing a green marble, first calculate the total number of marbles: 7 red + 9 yellow + 14 green + 10 purple = 40 marbles. The probability of choosing a green marble is the number of green marbles divided by the total number of marbles, which is 14 green / 40 total = 0.35. Thus, the experimental probability of choosing a green marble is 0.35, or 35%.
7/15 for blue marbles and 8/14 for the purple marbles this is dependent probability
Well, honey, there are 11 marbles in total, and 4 of them are blue. So, if you don't want a blue marble, that leaves you with 7 marbles to choose from. The probability of picking a marble that is not blue is 7/11. Hope that helps, sugar!
Probability of drawing a red marble = 4/16 = 1/4 Probability of drawing not a red marble = 1 - 1/4 = 3/4
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.
To find the experimental probability of choosing a green marble, first calculate the total number of marbles: 7 red + 9 yellow + 14 green + 10 purple = 40 marbles. The probability of choosing a green marble is the number of green marbles divided by the total number of marbles, which is 14 green / 40 total = 0.35. Thus, the experimental probability of choosing a green marble is 0.35, or 35%.
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%.
Well, honey, if you're reaching into that bag three times and each time you're pulling out a yellow marble and then putting it back in, the probability of picking a yellow marble each time is 8/21. Multiply that by itself three times because you're picking three marbles, and you get a probability of 512/9261. So, good luck with those yellow marbles, darlin'!
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.
