undergraduate and graduate students) in Dr. Chung’s Probability and Statistics
class is presented in Table below. One student is selected at random. Let
A = event the student selected is under 21,
B = event the student selected is over 30,
C = event the student selected is in his or her 20s, and
D = event the student selected is over 18.
Determine probabilities of the following events:
