Question

There are 40 students in a course: 15 freshmen, 8 sophomores, 12 juniors and 5 seniors. One student is selected at random to attend a workshop and report back to the class. What is the probability that the chosen student is a sophomore

Answer 1

Explanation:

There are 40 students in total, of which 8 are sophomores. So the probability of selecting a sophomore at random is:

P(Sophomore) = Number of Sophomores / Total Number of Students

= 8 / 40

= 0.2 or 20%

Therefore, the probability that the chosen student is a sophomore is 0.2 or 20%.
