12 blue 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.
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.
Sonya has no red blue marbles. All she has are 24 blue, 18 red and 12 green.

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

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.

If four red marbles make up a total of 13 marbles, each red marble is worth 13/4 = 3.25 marbles. Similarly, if three blue marbles make up 14 marbles, each blue marble is worth 14/3 = 4.67 marbles. This situation indicates a problem or inconsistency in the given information as it's not possible for the same marble to have different values based on color.
