A bag has 5 green marbles and 10 red marbles. Half of the red marbles are made of glass. A marble is selected at random from the bag. What is the probability that it is a red, glass marble?  How do I write my answer as a fraction in simplest form.

5 red marbles are made of glass.....there are 15 total marbles


So...the probability of selecting a red one made of glass   =  5 / 15  =  1 / 3
