Question

Determine the probability. At a certain college, there are 600 freshman, 400 sophomores, 300 juniors, and 200 seniors. If one student is selected at random, what is the probability that the student is a sophomore

Answer 1

4/15

Explanation:

The question asks to calculate the probability of a student picked from all is a sophomore.

What we do here is to find the total number of students first= 600 + 400 + 30 + 200 = 1,500 students

The probability of a sophomore is just placing the number of sophomores over the total number of students = 400/1500 = 4/15
