Question

A marble is randomly selected from a bag containing 3 red marbles, 3 blue marbles, and 3 green marbles. What is the probability that the selected marble is green?

Answer 1

1/3 of a chance

Explanation:

3 red, 3 blue, 3 green

that all adds to 9 marbles and there are 3 out of 9 marbles that are green.

the probability is 3/9 or 1/3

Answer 2

33.3% or 33% because you have to add all the marbles as your denominator then put the amount of green as your numerator and divide the 3 by 9 which equals 0.33333333 , take the decimal 2 places to the right you get 33.333333 which gives 33.3% but rounded up 33%
