Choose the correct choice from the following answers.
A) 15 B) 50 C) 55 D) 35 E) 65
You could pick 10 non-programmers, 2 male programmers, and 2 female programmers, and still not have 3 programmers of the same sex. But if you pick one more person, you must either pick a male or a female programmer, so the answer is 15.   15
