(2) Are the events women and the foreign car owner inependent ? Why or why not ?


Solution Preview

Let the number of employees be 100

Number of women = 60% of 100
= 60
Number of women who drive foreign cars = 1/3 of women
=1/3 0f 60
= 20
Number of women who drive domestic cars = 60-20

Solution Summary
