Harold sorted his jellybeans into two jars. He likes purple ones best and the black ones next best, so these are both in one jar. His next favorites are yellow, orange, and white, and these are in another jar. He threw all the rest in the garbage. Harold allows himself to eat only one jellybean from each jar per day. He wears a blindfold when he selects his jellybeans so he cannot choose his favorites first. What is the probability that Harold gets one black jellybean and one orange jellybean, if the first jar has black and purple jellybeans and the second jar has yellow, orange, and white jellybeans?

Make a tree diagram or an area diagram to represent the possible outcomes of selecting one jellybean from one jar and then one jellybean from the other.
