======D=======ND====Total
A------30----------18------48
NA-----70---------882----952
Total==100======900===1000
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
If the driver was in an accident, the probability that they were distracted is 30/48 or 0.625.
