Jeffrey Shallit posted the questions for the 2010 Bernoulli Trials at the University of Waterloo (Waterloo, Ontario, Canada). This is a math contest for undergraduates. You have to decide whether each of following questions are true or false.
Professor Shallit liked the questions because one or two made him think for a bit. Bully for him! When I looked at the list I can honestly say that none of them (not a single one) made me think of anything except what is a Bernoulli and why is he doing this to undergraduates?
I wonder if I could made up questions like this for biology students? I don't think so—the choices would have to be "mostly true" and "mostly false."
