A class of 100 students contains 20 freshmen, 30 sophomores, 40 juniors, and 10 seniors. I randomly select one student. What is the conditional probability they are a sophomore, given that they're an underclassman

Answer:

There would be a 30% chance that you would select a sophomore.

Explanation:

Since there is 100 students all together then 30 of the sophomores would be 30% of 100. So the answer is 30%
