Question

A bag has 6 blue marbles and 6 green marbles. Half of the green marbles are made of plastic. A marble is selected at random from the bag. What is the probability that it is a green, plastic marble? Write your answer as a fraction in simplest form.

Answer 1

3/12 because there is a total of 12 marbles and 3 of them are green plastic. Hope this helps xx

Answer 2

Total number of marbles = 6 + 6 = 12
Number of green plastic marbles = 6/2 = 3

P(green, plastic marble) = 3/12 = 1/4
