1. In the English language, only one number is spelled with its letters in alphabetical order. What is that number?
3. Imagine that you have three boxes: one containing two black marbles, one containing two white marbles, and the third containing one black marble and one white marble. The boxes were labeled for their contents--BB, WW, BW--but someone has switched the labels so that every box is now incorrectly labeled. You are allowed to take one marble at a time out of any box, without looking inside, and by this process of sampling you are to determine the contents of all three boxes. What is the smallest number of drawings needed to do this?
