There are 8 boys and 8 girls. If two groups are made from these boys and girls, what is the probability that one group will be only with girls?

What are the answer choices? This is important because we can sometimes find the correct answer by process of elimination (after we do a little work).

Also, to clarify, can the two groups have any number of people? Can one group have 2 people and the other group 14 people?

Must the two groups account for all 16 people? For example, can we have one group have 3 people and the other group have 7 people?

Given the ambiguity and lack of answer choices, I'm led to believe that this is not a GMAT question.

What is the source?

Cheers,
Brent

Have you made it on your own, no genuine Gmat question is so ambiguous?
