A sack contains red and blue marbles The ratio of red marbles to blue marbles is 4 to 3 If there are 16 red marbles in the sack how many blue marbles are in the sack?
12 blue marbles
If the ratio of red to blue marbles in a bag of 600 marbles was 7 to 5 how many marbles were blue?
250 Here's how: 1. Add the ratio: 7 + 5 = 12 2. Divide the total no. of marbles (600) by 12 = 50 3. The total no. of reds = 7 x 50 = 350 4. The total no. of blues = 5 x 50 = 250 (Total blues & reds = 350 + 250 = 600)
How do you Write a combination problem and solve it?
A combination problem essentially asks for two answers from different mathematical areas. A simple example could be, "A boy has a bag of marbles. Four marbles are blue. Three marbles are red. Five marbles are white. How many marbles does he have all together? What are the chances of picking a blue marble at random?" The two areas being addressed are simple addition and probability. There are a total of 12 marbles. There is a 1:3 chance of picking a blue marble at random.
If a bag contains 4 black 6 green and 2 yellow marbles and one marble is randomly drawn what is the probability that it is not black?
There are 8 marbles that aren't black, out of a total of 12 marbles, so the probability is 8/12 or 2/3.
In a bag contains 8 yellow marbles and 6 blue marbles what number of yellow marbles can you add to the bag so that the ratio of yellow to blue marbles is 2to1?
Four. The answer will be 12 to 6 which reduced is 2 to 1.
Five twelfths of the marbles in a bag are blue. What fraction of the marbles are not blue?
The answer is 7/12. This is because you just have to subtract 5/12 from 1/1 (12/12).
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%.
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?
Sonya has no red blue marbles. All she has are 24 blue, 18 red and 12 green.
A bag contains 12 marbles 8 marbles are red 4 marbles are blue if you draw one from the bag what is the probability that the marble will be blue?
Total ways to draw one = 24Number of ways to draw a blue one = 4Probability of drawing a blue one = 4/24 = 1/6 = 16 and 2/3 percent.
12 red marbles and 15 marbles are blue. if one marble is drawn from the bag What is the probabilitythe marble is not be red?
15/27. Simply take the probability of drawing a blue marble.
There are 4 blue marbles 1 yellow and 7 black in a bag what chance is there of picking a black?
7/12
If you have a black bag with 4 red marbles 6 green marbles 4 blue marbles and 10 white marbles what is the probability of pulling out a white marble from the bag?
Probability = number_of_white_marbles / total_number_of_marbles = 10 / (4 + 6 + 4 + 10) = 10 / 24 = 5/12 ~= 0.42
