A science class has 8 juniors and 4 seniors. The teacher will randomly select 2 students, one at a time, to represent the class in a committee at the school.
Given that the first student selected is a junior, what is the probability that the
second student selected will be a senior? *

4/11

Step-by-step explanation:

After selecting a student, the number of students will be 7 juniors and 4 seniors making a total of 7 + 4 = 11

So we have 4 seniors to be selected from a total of 11

Hence, the probability here will be number of seniors/number of students = 4/11
