There are
three times as many blue cubes as yellow cubes
and five times as many green cubes as blue cubes
Sarah takes at random a cube from the bag.

What is the probability that Sarah takes a yellow cube.
Give your answer in its simplest form.

please help me. ​

Answer 1

Answer:

Let's assume there is 1 yellow cube in the bag. Because there are 2X as many blue cubes that means there are 2 blue cubes. Because there are 4X as many green cubes (I believe cubes not balls) then that means there are 4 green cubes.

Therefore:

1y + 2b + 4g = 7 total cubes

The probability that you pick out the yellow cube in 1 try would be #y/total amt = 1/7.

Your answer is 1/7.
