There are only blue cubes, yelbow cubes and green cubes in a bag. 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 bag. what is the probability that sarah takes a yellow cube.

Let’s assume there is 1 yellow cube, so:

1 yellow cube, 3 (3x1) blue cubes, 15 (5x3) green cubes

1 + 3 + 15 = 19

Probability of Sarah taking a yellow cube would be 1:19
