Answer:
1/2
Step-by-step explanation:
The probability that the first student is a junior is 3/4, since there are 3 juniors and 4 total students.
The second student is not independent since there is only 2 junior remaining among 3 total students.
P(both juniors) = P(junior and junior) = (3/4).(2/3) = 6/12 = 1/2 = 0.5
