The class president collected data on 150 randomly selected 17-year-olds at his school. He surveyed students on if they had a job and driver's license. The results are shown below.

· 93 of the 17-year olds had a job

· 128 of the 17-year olds had a driver's license

· 76 of the students had both a job and a driver's license
