Do internal 301 redirects pass 100% link juice?

I know external 301s don't pass 100% link juice but what about internal 301s? e.g example.com/blog -> example.com - would 100% of the link juice be passed? Simply put, if wordpress is backbone of money site is it better to just install in root or can I get away with installing in directory?

Edit - After having realized the stupidity in my post I request that this post be deleted

It's not a stupid question as some people really do not know.

A 301 redirect is meant to be a permanent redirect that tells search engines that the URL has permanently changed. This will pass around 90-99% of the "link juice" to the new URL so long as it is an internal 301 redirect.

A 302 redirect, on the other hand, does not pass any link juice as a 301 redirect is just temporary.
