First off I think a mod should move this since I don't think this is the right place for this topic. So let P(x)= probability of having x boys. Then you want since there are no boys. there are ways to have one boy out of a group of 11 people.
So, if the question was like "A family has five children. The probability of having a girl is 1/2. What is the probability of having no more than 3 boys?" Is this how you would do that?
Yes, that's correct.
