Out of 10 persons working on a project, 7 are graduates. If 3 are selected, what is the probability that there is at least one graduate among them?	Choose the correct choice from the following: A) 5/7 B) 119/3 C) 5/120 D) 119/120 E) 5/6
P(at least one graduate) = 1 - P(no graduates)   = 1 - 3C₃/¹⁰C₃ = 1 - (1)/(10 * 9 * 8)   = 119/120   Answer: 119/120
