Final answer:
The probability that a randomly selected student lives in the dormitory of 239 people is 47.8%.
Step-by-step explanation:
To find the probability that a randomly selected student lives in the dormitory of 239 people, we need to know the total number of students at the college. Let's assume there are 500 students in total. The probability can be calculated by dividing the number of students living in the dormitory by the total number of students:
P(dormitory) = Number of students in dormitory / Total number of students
P(dormitory) = 239 / 500
P(dormitory) = 0.478 or 47.8%
