In Mrs. Jones' jewelry box there is 1 silver necklace, 2 gold necklaces, 1 silver ring, 2 gold rings, 1 silver bracelet and 1 gold bracelet. It is dark in the room and Mrs. Jones reaches into the box and pulls out one item at a time. What is the probability that after 3 choices she will have all silver jewelry? (Assume that she just pulls out the first thing she touches and does not try to tell what the item is by how it feels.)
