Question

A bag of marbles contains only yellow, blue and green marbles. There are 4 yellow marbles and 2 blue marbles, and 1/3 of the marbles are green. If a marble is picked out at random, what is the probability it will be blue? Please give an answer ASAP!

Answer 1

2/9

Explanation:

There are 4 yellow marbles and 2 blue marbles = 6 marbles

This is 2/3 of the marbles since 1/3 are green

2/3 of the total marbles are 6 marbles

2/3 * m = 6

m = 6 * 3/2 = 9

1/3 m = green marbles = 1/3 *9 = 3

4 yellow marbles and 2 blue marbles 3 green marbles = 9 marbles

P ( blue) = blue/total = 2/9
