Let's say there's a TOTAL of 100 students at this college.
50 percent of the total number of students are freshmen.
# of freshmen = 50% of 100 = 50
20 percent of the fresh-men are enrolled in the school of liberal arts...
Number of liberal arts freshmen = 20% of 50 = 10
...and, of these, 30 percent are psychology majors...
Number of liberal arts freshmen who are psychology majors = 30% of 10 = 3
What percent of the students at the college are freshmen psychology majors enrolled in the school of liberal arts?
3/100 = 3%
Answer: A
Cheers,
