Answer: 50%
Step-by-step explanation: To find the percentage of students that have taken fewer than 17 courses, count the amount of people that have taken 16 or less courses in college. After counting the people, you will find out that the number of people having taken less than 17 courses is 6. Divide 6 by the total number - 12 - to get 0.5 as a decimal answer. Finally, to convert to a percent, multiply 0.5 by 100 to get 50%.
