Understanding Mixed States, Pure States

Ahh, I see. Very helpful, thanks.

Is it true that a mixed state cannot be factored into a bra times a ket? Or in other words, it does not project onto a state, so it can't be written in the form |psi><psi|?
Right. That can be a definition of the truly mixed state.
