Please note that this question consists of three parts. Show all your work/explanation. Just giving the answer without adequate work/explanation may result in zero for the question.  A used car dealership posts cars for sale on their website. 85% of the cars have automatic transmission, 20% are all-wheel drive, and 15% have both features. A car is randomly chosen from this website.  Are having these two features (automatic transmission and all-wheel drive), mutually exclusive? Explain using the appropriate probability(ies).  What is the probability that it has neither of these features? If a car has automatic transmission, what is the probability that it is an all-wheel drive?
