Out of 11 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 the correct choice from the following answers
A) 5/17
B) 26/13
C) 26/31
D) 26/33
E) 5/33
P(at least one graduate) = 1 - P(no graduates)   = 1 - 7C₃/11C₃ = 1 - (7 * 6 * 5 )/(11* 10 * 9 )   = 26/33   Answer: 26/33
