A bag contains 7 lavender marbles, 11 turquoise marbles and 5 rainbow marbles. What is the chance of drawing a lavender marble? If a lavender marble is drawn then placed back into the bag, and a second marble is drawn, what is the probability of drawing a turquoise marble? Give solutions exactly in reduced fraction form, separated by a comma

7 + 11 + 5 = 23 marbles
7/23 is the first answer.
What do you get for the second answer? 
is it 11/23??

Right.
See  that's not so hard. :) 
really? i didn't think it was that easy...so it's 7/23 and 11/23???
