Answer:
Step-by-step explanation:
Part A can be seen in the attached picture below. Since there are 76 students that have both a license and a job we need to subtract 76 from each to get the amount that only have either a license or a job as seen in the table. Also we can see from the table that it sums up to 145 students, meaning that 5 students do not have neither a job or a license.
Part B, to calculate this we need to divide the amount of students that ONLY have a job by the total amount of students that have a job (since the rest of those students also have a license) Therefore:
17 / 93 = 0.1828
Now we can multiply this result by 100 to get the percentage.
0.1828 * 100 = 18.28%
