Final answer:
60% of college freshmen plan to study fields other than those listed.
Step-by-step explanation:
To determine the percentage of college freshmen who plan to study fields other than those listed, we need to use the information provided about the percentages of students studying different subjects. From the given data, we have the percentage of students studying technical (40.9%) and non-technical (48.6%) subjects. To find the percentage of college freshmen planning to study other fields, we subtract the percentage of students studying technical and non-technical subjects from the total (150.5% - 40.9% - 48.6% = 60%). Therefore, 60% of college freshmen plan to study fields other than those listed.
