Let the number of yellow cubes be x.

The number of blue cubes = 3x

The number of green cubes = 15x

Total number of cubes will be = x+ 3x +15x = 19x.


P(of chosing yellow cube) =
[tex] \frac{x}{19x} \\ \\ = \frac{1}{19} [/tex]

Answer:

1/19

Step-by-step explanation:

Let yellow cubes be x

Let blue cubes be x

Let green cubes be x

So let's interpret the question

3 times of blue than yellow means

3x----x

Fives times of green than blue which means 5(3x)

15x

So blue is 3x, yellow is x and green is 15x

Let's sum them up

3x+x+15x=19x

Probability of yellow is

x\19x

1/19

Since we are to leave our answer in fraction therefore the final answer is 1/19
