What about: 你们有儿子多少?
What about 男子? Is it somehow used?
Any reason for the word order? I wrote: 你们有儿子几个? but it got marked wrong
Numeral-classifiers (for e.g. 几个 or 一个) are always placed before nouns (儿子)
I cannot imagine using "you guys" to imply that I am speaking to more than one person, especially to a group of ladies! "You all" in my opinion, is a better choice of words for me to use.
