Question
Students at a local university have the option of taking freshman seminars during their first year in college. A survey of the freshmen revealed the following: Among the social science majors, 50% chose to take a freshman seminar; among the humanities majors, 65% chose to take a freshman seminar; and among the physical science majors, it was 30% . Among the freshmen, 50% are social science majors, 35% are humanities majors, and 15% are science majors. Freshmen make up 32%of undergraduates.
The percent of all freshmen enrolled in a freshman seminar is:
A) 0.523.
B) 0.5.
C) 0.32.
D) 1.
Explanation / Answer
The required answer is
0.5*0.5+0.35*0.65+0.15*0.30 = 0.523
What is done here is
50 percentage of amount of social science majors who chose to take a freshmen seminar = 0.5*0.5
35% of humanities majors = 0.35*0.65
15% of science majors = 0.15*0.30
sum all to get the required percentage
