Mummy and Daddy never talked about it. But Mrs Longbottom talks about it and she was at school while Daddy was although she was one year behind him. So I know there were muggleborns at school when Daddy was.

Mummy and Daddy were in Slytherin and Sarah says there were never any muggleborns in Slytherin but she also says the Houses have classes together and also clubs.

I wish I could still have a House but I wouldn't want it to be Slytherin, I think I would want to be in Ravenclaw like Sarah was.
