<dd><p>Draw samples from the geometric distribution.</p>
<p>Bernoulli trials are experiments with one of two outcomes:
success or failure (an example of such an experiment is flipping
a coin). The geometric distribution models the number of trials
that must be run in order to achieve success. It is therefore
supported on the positive integers, <code class="docutils literal notranslate"><span class="pre">k</span> <span class="pre">=</span> <span class="pre">1,</span> <span class="pre">2,</span> <span class="pre">...</span></code>.</p>

<div class="math notranslate nohighlight">
\[f(k) = (1 - p)^{k - 1} p\]</div>
<p>where <em class="xref py py-obj">p</em> is the probability of success of an individual trial.</p>
