You first have to count and see how many earrings she has in total

Then, count how many diamond earrings she has

anonymous · Answer

And then, put the number of diamond earrings over the total number of earrings she has in all

anonymous · Answer

To figure out which the probability of diamond earrings being picked depends on how many rings in total are in the box, and also on the number of DIAMOND earrings in the box. So it looks like there's 10 pairs of earrings with diamonds, and 19 earrings in total. So the probability of diamond earrings being picked are 10/19.
