the question is We're playing a popular board game about snatching up real estate in Atlantic City. I need you finish out the CapitalismHand class. First off, make sure it always rolls two D6s.

Here's a hint: When they say "First off, make sure it always rolls two D6s.", you probably will want to override __init__ so you can pass some specific arguments to the base class.

:warning: FYI: According to a moderator, explicit answers without any explanation are strongly discouraged by Treehouse.

Also, since the code has not been formatted for Markdown, what is being displayed is not correct.
