Since the probability is (more or less evidently) less than 3/4 for
vertices i.i.d. uniformly in a square and since the probablility
approaches 1 as the (1 x 1) square is stretched to become a (1 x L)
rectangle (where L --> \infty). If one believes in continuity of
the resulting probability as a function of L, then the answer is
"Yes, there is a bounded rectangle for which the probability = 3/4."
Indeed, such L isn't very big at all.
