What is the probability of selecting 4 red or 5blue marbles?
The probability of selecting 4 red marbles or 5 blue marbles depends on how many marbles there are altogether, and how many of the total number of marbles are red and how many are blue.
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.
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 sack contains red and blue marbles The ratio of red marbles to blue marbles is 43 If there are 16 red marbles in the sack how many blue marbles are in the sack?
This problem doesn't lead to a whole number solution. Are you sure you copied it correctly? Maybe you meant the ratio is 4 to 3. In that case: red/blue = 4/3 blue/red = 3/4 blue = (3 * red) / 4 = (3 * 16) / 4 = 12 blue marbles

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
The number of red marbles varies inversely as the square of the number of blue marbles when there were 4 reds there were 20 blues How many reds would there be if there were only 4 blues?
Indirect variation: the numbers of red marbles = k/the square of blue marbles, where k is the coefficient of the variation. 4 = k/202 4 = k/400 1600 = k Let the number of red marbles be x. x = k/42 x = 1600/16 x = 100 Thus, if there were 4 blue marbles, would be 100 red marbles.
Explain how four red marbles can make up 13 of a group of marbles and three blue marbles make up 14 of the same group?
There has to be 12 marbles in the group. If 4 are red that is 1/3 of 12 and if 3 are blue that is 1/4 of 12. The rest can be any color. That is how you explain how four red marbles can make up 1/3 of a group of marbles and three blue marbles make up 1/4 of the same group :)
If 2 marbles are drawn simultaneously at random from a box containing 6 red marbles 4 white marbles and 4 blue marbles what is the probability that neither of the marbles is white?
