In a bag there are 8 red marbles 4 blue marbles and 6 green marbles write the ratio of red marbles to green marbles?
8:6
If you have 6 red marbles 3 yellow marbles and 5 green marbles in a bag what is the probability of picking a blue marble out?
0No blue marbles in the bag.
A bag contains six blue marbles seven red marbles and four green marbles If four marbles are drawn randomly determine the probability that three are green?
It is 1248/57120 = 13/595 = 0.0218 approx.
A bag contains 5 red marbles 3 blue marbles and 2 green marbles What is the probability of pulling out two different color marbles?
5/10
A bag contains 11 blue marbles 10 purple marbles 17 red marbles 15 green marbles and 3 yellow marbles What is the probability of pulling out a blue or a red marble?
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%.

1/3
What is the number of each colour of marbles in a bag of 76 marbles if the ratio of red marbles to green marbles is 2 to 3 and the ratio of green marbles to blue marbles is 9 to 4?
The ratios are: red : green = 2 : 3 = (2×3) : (3×3) = 6 : 9 green : blue = 9 : 4 → ratio of red : green : blue = 6 : 9 : 4 There are 6 + 9 + 4 = 19 parts 76 marbles ÷ 19 parts = 4 marbles per part → red: 6 parts = 6 × 4 marbles per part = 24 red marbles → green: 9 parts = 9 × 4 marbles per part = 36 green marbles → blue: 4 parts = 4 × 4 marbles per part = 16 blue marbles To check: red + green + blue = 24 marbles + 36 marbles + 16 marbles = 76 marbles in the bag.
Example of a ratio?
If you had a bag of marbles, and there were two colours - red and green - and the ratio of the coloured marbles is two times the amount of green marbles to red marbles, you would have a ratio of 2:1
If there are 50 marbles 15 are blue 8 are yellow and 27 are red what is the probability of green?
There are 15 blue marbles, 8 yellow marbles and 27 red marbles for a total of 50 marbles. Since there are no green marbles in the lot, It is impossible to pull a green marble from the lot. The is no probability whatsoever! "There just ain't no green ones to pull."
