Name of POW: "Mislabeled Marbles"
Problem
Three containers are labeled BB, WW, and BW. One container has two black marbles, another two white marbles, and the third a black and a white marble. Each of the containers is incorrectly labeled!
You are allowed to take out one marble at a time (without looking inside) until you are sure of the contents of all three containers. Devise a plan to find the contents using as few marbles as possible.
