c. What is the probability that a respondent is male and drives a minivan?

d. What is the probability that a female respondent drives either a truck or an SUV?

e. If it is known that an individual drives a car, what is the probability that the individual is male?

f. If it is known that an individual is female, what is the probability that she drives an SUV?
