There are three tubs of jelly beans

They're all opaque, so you can't see what's in them. You know that one tub contains red jelly beans, one tub contains green jelly beans and the other contains a mixture of both. You also know that all of the tubs are incorrectly labelled.

How many times do you need to reach for a jelly-bean before you know which tub is which, and why?
