Assume you have three boxes, one with two black marbles, one with two white marbles, and one with one black marble and one white marble. The boxes were labeled for their contents – BB,WW, and BW – but someone swapped the labels, and now every box is improperly labeled. You are only permitted to take one marble out of each box at a time, without peeking inside, and you must use this sampling method to ascertain the contents of all three boxes.

What is the smallest number of drawings required to complete this task?
