[math-fun] David Blaine, 37

A friend of mine was just watching David Blaine on TV. One of his tricks was to say "Pick a number between 1 and 50. Be sure it is composed of two digits; they have to be odd and not duplicates of each other." Well, that permits only 13, 15, 17, 19, 31, 35, 37, 39. The guy on TV and my friend chose 37, which is what Blaine guessed. Do people tend to choose 37 from this set?
