There are 14 freshmen and 18 sophomore students in a classroom. We randomly select two
students.
Suppose the students were selected with replacement.
a) If the first student was a freshman, what is the probability that the 2nd student is also a
freshman?
b) If the first student was a sophomore, what is the probability that the 2nd student was a
freshman?
Suppose the students were selected without replacement.
c) If the first student was a freshman, what is the probability that the 2nd student is also a
freshman?
d) If the first student was a sophomore, what is the probability that the 2nd student was a
freshman?
