Question

There are only blue ,yellow cubes and green cubes in a bag there are 5 times as many blue cubes as yellow cubes and there are 5 times as many green cubes as blue cubes sarah takes at random a cube from the bag what is the probability that sarah takes out a yellow cube

Answer 1

1 / 31

Explanation:

Given that:

Yellow (y) ; Blue (b) ; Green (g)

b = 5y

g = 5b

Assume :

Number of yellow cube = 1

y = 1

b = 5

g = 5*5 = 25

Probability = (required outcome / number of total possible outcomes)

P( picking a yellow) = number of yellow / total number of cubes

Total number of balls = (1 + 5 + 25) = 31

P(picking a yellow) = 1 / 31
