====CD+====CD-
AC+ --25-------------65
AC- ------------------35
-------45---------------100
given for 100 cars. Fill in the rest
====CD+====CD-=======
AC+ --25-----40----------65
AC- --20------15----------35
-------45------55--------100
Given a car has AC(65), probability it has a CD player is 25/65 or 5/13.
