There are only blue cubes, yellow 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 a random cube from the bag what is the probability sarah takes out a yellow cube? give your answer in its simplest form

Step-by-step explanation:

Let x represent the quantity of yellow cubes

Yellow: x

Blue: three times yellow --> 3x

Green: five times blue --> 5(3x) = 15x

Yellow + Blue + Green = Total cubes

    x      +   3x  +    15x   =       19x

reduce the friction between its moving parts
