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%.

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
What is the theoretical probability of randomly drawing a green marble if there are 5 red marbles 8 blue marbles and 12 green marbles in a bag.?
The theoretical probability of randomly drawing a green marble can be calculated by dividing the number of green marbles by the total number of marbles in the bag. In this case, there are 12 green marbles out of a total of 5 red marbles + 8 blue marbles + 12 green marbles, which is 25 marbles in total. Therefore, the theoretical probability of drawing a green marble is 12/25 or 48%.
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."
What is percent to pick red marble 2 green marbles 2red marbles?
To calculate the percentage of picking a red marble from a total of 4 marbles (2 green and 2 red), you divide the number of red marbles by the total number of marbles and then multiply by 100. So, the calculation is (2 red marbles / 4 total marbles) × 100 = 50%. Therefore, the percent chance of picking a red marble is 50%.
1 Sonya has a bag of 54 different-colored marbles The marbles are blue red and green and are on the ratio 4 3 2 How many marbles does Sonya have that are a red blue?

Why is mixing red and green marbles a physical change?
Mixing red and green marbles is a physical change because the marbles retain their original properties and can be separated back into red and green marbles. The act of mixing does not alter the chemical composition of the marbles, making it a reversible physical change.

In a bag of marbles you have three green two yellow six blue and nine red marbles. What is the probability of picking a red marble from the bag?
To find the probability of picking a red marble, first determine the total number of marbles in the bag, which is 3 (green) + 2 (yellow) + 6 (blue) + 9 (red) = 20 marbles. The number of red marbles is 9. Therefore, the probability of picking a red marble is the number of red marbles divided by the total number of marbles, which is 9/20 or 0.45.
