Henry wrote a note on a piece of paper, folded it two times, and wrote “FOR MOM” on the top. Then he unfolded the note, added something to it, randomly folded the note along the old folding lines (not necessarily in the same way as he did it before) and left it on the table with random side up. Find the probability that “FOR MOM” is still on the top.
