Opinions? Please?

So I was wondering how everyone's view was on this.. My husband thinks hell never be able to have a girl bc his dad had nothing but boys! Does that matter? On my side my grandmother had girl then boy; my mom- me then my brother; my uncle- girl then boy. On his side his grandfather had all girls and his girls had all boys so I was wondering if that meant we are more likely for another boy or if we had a 50/50 chance like everyone else
