Question

Original parts for older cars can be hard to find. A restorer decides to visit local junkyards to see if they have a dashboard panel that he needs for a restoration project. There are seven junkyards in a 100 mile radius. The restorer doesn't know it, but two of those junkyards have the panel he needs. What is the probability that the restorer randomly visits three junkyards that do not have the dashboard panel he needs?
