A survey of 200 recent high school graduates found that 170 had driver licenses and 108 had jobs. 21 graduates said that they had neither a driver license nor a job. a. Draw a two-way frequency table to represent the situation.
b. If one of these 200 graduates is randomly selected, what is the probability that he or she has a job and no license?
c. If the randomly selected graduate is known to have a job, what is the probability that he or she has a license?
