WebJun 7, 2014 · 1. In each iteration of Miller-Rabin you need to choose a random number. If you are unlucky this random number doesn't reveal certain composites. A small example of this is that 2^341 mod 341 = 2, passing the test. But the test guarantees that it only lets a composite pass with probability <1/4.
