Published 27 Nov 2013 in physics.data-an, math.PR, and physics.pop-ph

Abstract: Suppose that in a multiple choice examination the leading digit of the correct options follows Benford's Law, while the the leading digit of the distractors are uniform. Consider a strategy for guessing at answers that selects the option with the lowest leading digit with ties broken at random. We provide an expression for the probability that this strategy selects the correct option.
