     In the following table, <span class="emphasis"><em>p</em></span> is the probability that
          any one trial will be successful (the success fraction), <span class="emphasis"><em>k</em></span>
          is the number of failures, <span class="emphasis"><em>p</em></span> is the probability and
          <span class="emphasis"><em>q = 1-p</em></span>, <span class="emphasis"><em>x</em></span> is the given probability
          to estimate the expected number of failures using the quantile.
