and 35 percent BMWs. Of the Lincol? have been trying to do this problem. end up with the wrong answer. could someone help? thanks!
Assume that the car lot contains 20 percent Lincolns,
45 percent Porches, and 35 percent BMWs. Of the Lincolns,
70 percent have two airbags, 60 percent of the Porches have
two airbags, and 90 percent of the BMWs have two airbags. Furthermore,
70 percent of the Lincolns, 40 percent of the Porches, and
30 percent of the BMWs are white. The property of being white is
independent from having two airbags. You are assigned a car at random.
If the car has two airbags and is white, what is the probability that it is a Lincoln?
