Quantum mechanics tells us that if a particular event can happen in two or more indistinguishable ways, we must first sum the probability amplitudes before squaring to obtain a probability. Because these amplitudes can be negative, it is possible for events that we would intuitively expect to be possible to have zero probability. If the BS is more or less reflective than 50, these two amplitudes no longer have the same magnitude but are still opposite in sign, meaning that the probability is nonzero but less than one would naively expect
