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?
