Question

There are only blue cubes, yellow cubes and green cubes in a bag.
There are
twice as many blue cubes as yellow cubes
and four times as many green cubes as blue cubes.
Hannah takes at random a cube from the bag.
Work out the probability that Hannah takes a yellow cube.

Answer 1

Answer:

Step-by-step explanation:

Let the yellow cubes be x

according to the question ,

blue  cubes r twice of yellow

green is 4 times of blue

 

yellow = x

blue = 2x  

green-8x            

Ratio:

Yellow : Blue : Green

  1       :   2    :     8

Probability of getting (Yellow) = 1/11
