Transcribed Image Text:You are a paranoid delusional statistician with far too much time on your hands. One day, you sit
down to have a bowl of soup. This bowl of soup happens to be Tic-Tac-Toe themed, meaning
that you have some noodles that are shaped like an X, and some that are shaped like an O. As
you stir your soup, you notice that this bowl seems to have a particularly high number of X-

trying to give you a message, possibly warning you of the dangers of x-rays. You jump out of
your seat and run to get your x-ray-proof cape, and then you pause for a moment and think that

you
find:
