From the assumption that the atoms decay in a random manner. This
gives unpredictability. The other quantum assumptions say that
the decays of the various atoms are independent, and that the
decay is at an exponential rate.

The msin assumption in this is that the probability that an
atom which has not decayed by time T will still have a probability
of decay between T and U which is independent of anything which has
happened before time T, and only depends on U-T.
