Question

There are 13 freshmen and 16 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? 0.4483 b) If the first student was a sophomore, what is the probability that the 2nd student was a freshman? 0.2473 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? 0.1921 d) If the first student was a sophomore, what is the probability that the 2nd student was a freshman? 0.256 Be sure to include at least 4 decimal places, if needed.
