Out of 8 persons working on a project, 4 are graduates. If 3 are selected, what is the probability that there is at least one graduate among them?
Choose one:
A) A)5/7
B) B)5/4
C) C)5/14
D) D)5/6
E) E)9/14
P(at least one graduate) = 1 - P(no graduates)   = 1 - ⁶C₃/¹⁰C₃   = 1 - (6 * 5 * 4)/(6 * 7 * 8)   = 9/14   Answer:9/14
