Out of 10 persons working on a project, 5 are graduates. If 3 are selected, what is the probability that there is at least one graduate among them?  Choose the correct answer
A) A)5/7	B) B)5/12	C) C)5/1	D) D)1/12	E) E)5/3
P(at least one graduate) = 1 - P(no graduates)   = 1 - 5C₃/¹⁰C₃   = 1 - (3 * 5 * 4)/(10 * 9 * 8)   = 1/12   Answer:1/12
