A bag contains 6 purple marbles, 7 azure marbles and 10 orange marbles. What is the chance of drawing an azure marble?
7 azure marbles out of 6+7+10 or 23 marbles.  That's a probability of 7/23

If an azure marble is drawn then placed back into the bag, and a second marble is drawn, what is the probability of drawing a purple marble?
Drawing the azure marble and putting it back has no effect and can
be ignored.  

6 purple marbles out of 23 marbles.  That's a probability of 6/23.

Give solutions exactly in reduced fraction form, separated by a comma.

7/23, 6/23
