Broken Window

One snowy night, Sherlock Holmes was in his house sitting by a fire. All of a sudden a snowball came crashing through the window, breaking it. Holmes got up and looked out just in time to see three neighborhood kids who were brothers run around the corner. Their names were John Crimson, Mark Crimson, and Paul Crimson.

The next day Holmes got a note on his door that read:

“? Crimson. He broke your window.”

Which of the three Crimson brothers should Sherlock Holmes question about the incident?

He should question Mark. The note read: “QUESTION MARK Crimson. He broke your window.”

Roll a Pencil

You roll a 5 sided pencil on the table. On one of its sides, it is written “HB Pencil”, the others are blank. What is the chance that the side with text on it ends up straight on top?

The chance is 0%. Since the pencil has an odd number of sides, it is impossible that any of them ends up straight on top.
