Probability a driver will be in an accident is 48/1000 or 4.8%.  This can be read right off the table, which has 9 cells.  We get the bottom three from the 10% probability a driver is distracted, and we get the top left from the distracted-accident, the center from non distracted-accident.  The rest can be filled in
